Question 4(b)
[Maximum number: 2]
A squash ball is made of rubber and used to play a game called squash.
A student observes that the squash ball bounces higher after its temperature increases.
The student designs an investigation to see how the temperature of the ball affects the maximum height after it bounces.
The diagram shows the ball at its maximum height after it bounces.
Determine the distance the ball moves from the floor to its maximum height.
Assume the ball does not change shape when it bounces.
[1 cm on diagram = 4 cm in laboratory]
