UNIFORMLY ACCELERATED MOTION Problem-Solving 1. A car traveling at 22.4 m/s skids to a stop in 2.55 s. Determine the skidding distance of the car (assume uniform acceleration). 2. A bike accelerates uniformly from rest to a speed of 7.10 m/s over a distance of 35.4 m. Determine the acceleration of the bike. 3. An engineer is designing the runway for an airport. Of the planes which will use the airport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway? 4. If basketball player has a vertical leap of 1.29 m, then what is his takeoff speed and his hang time (total time to move†¦show more content†¦Hammy has jumped with initial velocity of 5 m/s at an angle of 250 for 1 second. Will he be able to reach the ice block? If not maintaining the same velocity and hang time, what should be the angle of his take off to be able to reach the ice block? 2. The target is located 100 m away from the cannon. The target is aimed at 250 angle. The target was hit after 2s. What is the velocity of the cannon ball upon being fired? At what distance from the ground is the peak of the projectile? 3. A bullet is fired with a velocity of 200 m/s at an angle of 450 from the horizontal, after approximately 2s, the target is hit. How far is the target placed? B. Target is higher than Launch point 1. The horizontal distance of the cannon from the target is 100 m away. However the target is on top of a hill with a height of 15 m. The cannon is aimed at 500 angle from the horizontal and upon firing cannon ball has a velocity of 150 m/s. Will the target be hit by the cannon? 2. Your opponent is located at a horizontal distance of 5m. But he is elevated at a height of 3m. Your cannon always fire the cannon ball at a velocity of 120m/s, the hang time of the cannon ball is 1.5 s. What should be your aim angle to be able to hit your opponent? With that aim angle, how high is the peak of the projectile? 3. You are located uphill at a height of 6m from the ground. Your opponent is at a horizontal distance of 260 m away fromShow MoreRelatedProblems on Physics613 Words   |  2 Pagesï » ¿Work out the following problems. Be sure to show your work in detail. See the hand out uploaded for examples of how the problems should be solved and presented.   1. A 55 gal. drum of organic solvent, full and sealed, weighs 400 lbs. The empty drum weights 40 lbs. What is the density of the solvent, in kg/L? What is its specific gravity? Density = p = mass/volume Mass of solvent = 400 lbs 40 lbs = 360 lbs = 360 lbs * (0.45359237 kg/lbs) = 163.29 kg 1 pound = 1 lbs = 0.45359237 kg (online conversionRead MoreSolving The Physics Of The Problem1393 Words   |  6 Pagesdimensionality of the dataset for viewing, which may help researchers in better understanding of the physics of the problem. Here, an expert needs to be careful while choosing a certain algorithm and associated parameters for a specific case. Additionally, an expert needs to be very careful while interpreting the findings from these algorithms. One must use the technical aspects regarding the basic physics of the problem so that their results are meaningful and for it to be accepted by the materials researchRead MoreThe Education and Skills Needed to Become a Physicist Essay920 Words   |  4 Pagescuriosity to be devoted to their pathway, which can be obtained as a imaginative child. From there, Dr. Michio Kaku states the physical learning begins. In high school, he thinks the best opportunities lie in physics books and science fair projects. (1) These practices i ntroduce the basis of physics. If needed, an interview with a physicist can help devote the passion to the job. A basic math knowledge is required so Calculus and other math classes will aid the journey. Also, good grades throughout theRead MorePlank, Einstein and Black Body Radiation1400 Words   |  6 Pagesscientific research. Towards the end of the 19th century physics was mostly thought to be at an apex. One man at the time, William Thomson Kelvin [cited by Glen Elert in The Physics Hypertextbook], said along the lines of â€Å"There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.† This statement was to quickly become fiction with the beginnings of the 1900s. Two major problems in physics were still apparent; Theories on the luminiferous ether. ThatRead MoreFeasibility Report On Instructions For Building A Folded Paper985 Words   |  4 PagesPHYS 101. Problem PHYS 101: Physics for the Nonscientist is a course that aims to introduce the â€Å"nature of physical universe and the application of physical principles to life in the modern world† at Iowa State University (ISU Catalog). According to its syllabus, PHYS 101 is a 3 credits course with only lectures but not labs. Hence, the students in the course will not have the opportunity to experiment with the knowledge learned from lectures. It is almost impossible to learn physics just by theoriesRead MoreI Am Interested Into Learning1244 Words   |  5 Pageshave struggled with Calculus 1 and with Physics 1 and while initially that was very discouraging and made me want nothing to do with either subject, I now feel that struggling through those subjects may be the best thing I can do for myself, especially if my goal is to become an engineer. At the beginning of the year, I told my roommates that I wanted nothing to do with Physics or Calculus after this semester and yet now, I find m yself enrolled in both Physics 2 and Calculus 2. I have enjoyed bothRead MoreQuantum Mechanics and Islam Essay1602 Words   |  7 Pages Introduction Quantum mechanics or also known as quantum physics is a field of science which studies the behaviour of particles at sub-atomic level. This theory tells us that short-lived pairs of particles and their antiparticles are constantly being created and destroyed in an apparently empty space. In quantum mechanics the weird behaviour of electrons are not accurately explained and until now not a single theory is acceptable by the whole scientific community to postulate the phenomena. TheRead MoreThe Current Status Of Galaxy Formation1589 Words   |  7 PagesThe field of physics encompasses a variety of topics and sub-disciplines which include astronomy, cosmology, and particle physics, to name a few. As a student in the physics field, it is important to understand how physicists actually write and make arguments in their respective disciplines. By being able to analyze and rhetorically inspect an article, the material becomes more comprehensible and some potential implications of the writing begin to resound with the reader. The more we learn aboutRead MoreThe View Of The Leaning Process771 Words   |  4 Pagesphysicist and mathematician Isaac Newton, most famous for his law of gravitation, was instrumental in the scientific revolution of the 17th century; Italian sci entist and scholar Galileo made pioneering observations that laid the foundation for modern physics and astronomy and ; Albert Einstein was a German-born physicist who developed the general theory of relativity, among other feats. He is considered the most influential physicist of the 20th century. These scientists are the inspiration to my philosophyRead MoreWhen Diving Into The Details Of Gravitational Theories800 Words   |  4 Pagestheory has the negative norm state called ghosts which allow the probability to be negative and hence breaks the unitarity. In fact, as back as in 1850, Mikhail Ostrogradsky showed that presence of time derivatives higher than two will lead to the problem of ghosts [35]. Combining all these ideas, Horava added only the terms containing higher spacial derivatives while keeping the time derivatives to second order. Also the power-counting renormalizability restricts the number of spatial derivatives
