Elastic and Plastic Behaviour

Elastic and Plastic Behaviour problem 7

Jasper first shoots a ball with an elastic band on his catapult. The ball travels 3 m away from him. He then shoots the same ball with the same catapult and the ball moves 4.5 m away. If he shoots the balls at the same angle, in which case does the elastic band on the catapult have more elastic energy? Explain the answer.
