Three identical cars are being unloaded from an automobile carrier. Cars B and C have just been unloaded and are at rest with their brakes off when car A leaves the unloading ramp with a velocity of 6 ft/s and hits car B, which hits car C. Car A then again hits car B. The velocity of car B is 5.25 ft/s after the first collision, 0.630 ft/s after the second collision, and 0.709 ft/s after the third collision. Determine: a. the final velocities of cars A and C
b. the coefficient of restitution for each of the collisions

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
