(a)[1]
On Fig. 1.1, draw the position of the ball at the moment it is released.
(b(i))[2]
Calculate $t_{av}$, the mean value of $t$. Give your answer to two decimal places.
(b(ii))[1]
Suggest why the value for $t_{av}$ is not stated to more than two decimal places.
(c(i))[1]
The acceleration due to free-fall $g$ is given by the equation $g = \frac{2h}{t_{av}^2}$, where $h = 1.000\,\text{m}$. Calculate a value for $g$.
(c(ii))[2]
Another student suggests that, to obtain a more accurate value for $g$, the ball should be released from a height greater than 1.000 m. Explain why this student is correct.
