A ball is thrown vertically upwards towards a ceiling and then rebounds, as illustrated in Fig. 3.1. [Figure 3.1] The ball is thrown with speed 9.6 m s⁻¹ and takes a time of 0.37 s to reach the ceiling. The ball is then in contact with the ceiling for a further time of 0.085 s until leaving it with a speed of 3.8 m s⁻¹. The mass of the ball is 0.056 kg. Assume that air resistance is negligible.
