Show that the ball reaches a highest point of $4.7\,\text{m}$ above the ground.
The man does not catch the ball as it comes back down. Calculate the time taken for the ball to drop from its maximum height to the ground.
The ball is released from the man’s hand at time $t = 0$ and lands on the ground at time $t = T$. On Fig. 3.2, sketch a graph to show how the velocity $v$ of the ball varies with time $t$ from $t = 0$ to $t = T$. Numerical values of $v$ and $t$ are not required. Take $v$ to be positive upwards.
State what the gradient of the graph in (c) represents.
The man now throws a second ball with the same velocity and from the same height as the first ball. The mass of the second ball is greater than that of the first ball. Assume that air resistance is still negligible. For the first and second balls, compare the magnitudes of their accelerations.
