Two railway trucks are travelling in the same direction and collide. The mass of truck X is 2 . 0 × 10 4 kg and the mass of truck Y is 3 . 0 × 10 4 kg . This graph shows how the velocity of each truck varies with time. (b) State and explain whether the collision of the two trucks is an example of an elastic collision.

Initial kinetic energy before 2.0 second = 2 × 10 4 × 5 2 + 3 × 10 4 × 1 2 2 J =total initial kinetic energy= 2 . 65 × 10 5 J Final kinetic energy after 3.6 second = 3 × 10 4 × 3 2 + 2 × 10 4 × 2 2 2 J Total final kinetic energy= 1 . 75 × 10 5 J Collision is not elastic because the total kinetic energy has decreased in the collision
