A truck P, loaded with ore starts from rest and runs freely down a slope on a track from K to L. The mass of the loaded truck P is 900 kg. The distance from K to L is 101,4 m and the height of point K is 33,8 m. The track is horizontal from L onwards. The entire track is frictionless. At L truck P collides with a stationary truck Q, mass 337,5 kg. After the collision the truck P continues to move at a sped of 19,5 m.s-1 . a. Calculate the velocity at which truck Q moves after the collision. b. Was the collision elastic or inelastic? Prove your answer with a calculation.
