Question

A truck (mass 3216 kg) and a car (2372 kg) collide. The truck moves at a speed of 25 m/s towards the stationary car. Assuming this is an elastic collision, how fast will the bruck be going after the collision?

A cylinder initially traveling at 4 m/s rolls up a hill inclined at 53 degrees. What is its vertical height when it comes to rest?

A satellite rotates starting from rest for 2.3 seconds with an angular acceleration of 3.8 rad/s². How many revolutions has the satellite undergone in this time interval?
