- Under what condition is the energy lost during a collision maximum? A) e=1.0 B) e = 0.0 C) e=-1.0 D) Collision is non-elastic.Let a mass of 3.0 kg be standing still and a secondmass of 5.0 kg come along and hit it with velocity 4.0 m/s. Supposethe smaller mass moves off with a speed of 5.0 m/s.a) Draw a diagram to describe the situation before the collision.b) What is the velocity of the 5.0 Kg mass after the collision?c) Draw a diagram to describe the situation after the collision.d) What type of collision is it? Support your answer with calculations from Lawof Conservation of Momentum, and Law of Conservation of Energy.1) A 100 g cart initially moving at +0.5 m/s collides elastically from a stationary 180 g cart. a) Using the equation in the theory, calculate the final velocity of the 100 g cart. b) Calculate the change in the momentum of the 100 g cart. c) Since this is an elastic collision, total momentum must be conserved. Using your answer for part b, calculate the final velocity of the 150 g cart.
