Blocks A and B stick together after the impact. You may neglect friction during the impact. After the impact, the velocity of blocks A and B decreases due to friction. The coefficient of kinetic friction between all surfaces is μ = 0.20. Use conservation principles (including the system diagrams) to answer the following. (a) Determine the velocity of block A and B immediately after A hits B. (b) Determine the impulse exerted by block A on block B during the impact. (c) Determine the time required for the velocity of the blocks to drop to 1 m/s after the impact. (d) Determine the distance traveled by the blocks during this time interval.

: Tom is interviewing for a new job – a test driver. He was asked to determine whether a vehicle built to test the effects of Problem 1 high accelerations on people is safe. The car moving at a speed of 20 m/s runs into a piston that compresses the air in a cylinder and stops the car in 0.30 m. The 70-kg passenger stops in the same distance due to the force of shoulder straps and seat belts on her body. Draw free-body diagram for the passenger when he is slowing down to a stop inside a car. Assume that the force of the shoulder straps and seat belt is horizontal. Do not forget to draw acceleration vector as well. Choosing the passenger as your system and applying energy conservation law, find the work that the force of shoulder straps b. and seat belts did on his body in this process. C. Now that you have determined the work in the previous part, determine the magnitude of the average force of these restraints on the person during the stop.
