- 32)4. In a perfectly inelastic collision, two objects collide and stick together. Is momentum conserved in the collision? Is energy conserved? Why or why not?3. This problem refers to the figure below: mmm There are 3 identical bobs of mass m hanging side-by-side. Two are then lifted to a height of h and released. The collisions in this problem are elastic. Answer the following questions: (a) Let's call the initial and final state immediately before and after the collision, respectively. Write down the initial momentum and kinetic energy of the system in terms of m and h. (b) Show that, after the collision, the left and center bobs rise to height h while the right bob becomes stationary. In particular, show that the center bob acts as if it were swinging freely as a lone pendulum.
- A 1500 kg car traveling to the north is slowed down uniformly from initial velocity of 20 m/s by a 6000 N braking force acting opposite the car’s motion. Use the impulse-momentum theorem to answer the following questions What is the car’s velocity after 2.00 s? How far does the car move during 2.00 s? How long does it take the car to come to a complete stop?About ELASTIC collisions: (both questions are related to each other.) Please answer it short and easy to understand What happens if the cars have the same mass but one car has twice the velocity? If one car has twice the mass as the second car, can you still get the cars to bounce back equally? Explain how.A 1500 kg car accelerates from 15 m/s to 25 m/s. Calculate the impulse experienced by the car.
