Question statement

A ball is thrown upwards, and moves according to the equation $\displaystyle{\frac{d^2z}{dt^2}=-g}$
(where $z(t)$ is distance in metres measured upwards from the ground and the constant acceleration of gravity, $g$ , is given as $9.81\;m/s^2$ ).

The ball is projected upwards with a speed $\var{v}\;m/s$ .

Give any introductory information the student needs.

Ask the student a question, and give any hints about how they should answer this part.

Input the vertical distance $z$ as a function of $t$.

Note that at $t=0$ we have $z=0$ and that $\displaystyle \frac{dz}{dt}=\var{v}m/s$.

Input gravitational acceleration as $g$.

$z=$ Unnamed gap
