3) A 1000 kg car is traveling due east with a speed of 10 m/s. A 1500 kg truck is traveling due north at a speed of 15 m/s. These cars undergo a purely inelastic collision. a) Is the linear momentum of the system conserved in this collision? What does this tell you about the net external force on this system? Explain your answer(s). b) Find the speed and direction of the masses just after collision. c) Is the kinetic energy of the system conserved? Verify your answer by calculating the initial and final kinetic energies. d) If the cars slide to a stop in 25 meters after they collide, how much work was done by friction? What was the average force of friction needed to bring the cars to rest? e) What impulse was delivered to the cars by the road? How long (in time) did it take for the cars to come to rest?
A 750 kg car is stalled on an icy road during a snowstorm. A 1000 kg car traveling eastbound at 14 m/s collides with the rear of the stalled car. After being hit, the 750 kg car slides on the ice at 4 m/s in a direction 30∘ north of east. What is the magnitude of the velocity of the 1000 kg car after the collision? What is the direction of the velocity of the 1000 kg car after the collision? Calculate the ratio of the kinetic energy of the two cars just after the collision to that just before the collision. (You may ignore the effects of friction during the collision.)
34. Imagine that a wood block is sliding along the surface of a desk. Can the frictional forces involved in this interaction change the momentum of the two-body system thought of as the Earth (including the desk) and the block? Yes, because it will provide a negative impulse to the block. Yes, because it will cause a negative impulse to the Earth. No, because the net force on the block will be zero. No, because there is no net external force on the system.
