A ball is projected from the ground at point X. The ball then reaches its maximum height at point Y before landing on lower ground at point Z. The diagram shows the path of the ball. The ball leaves the ground at X with a kinetic energy of 5.2 J. The ball has a kinetic energy of 9.6 J when it hits the ground at Z. The weight of the ball is 2.0 N. The vertical height of Y above Z is 4.0 m. Air resistance is negligible. What is the vertical height of Y above X?

1. A1.8 m
2. B2.0 m
3. C2.2 m
4. D2.6 m
