## Homework Statement

A ball is thrown vertically upwards and caught by the thrower on its return. Sketch a graph of velocity (taking the upward direction as positive) against time for he whole of its motion, neglecting air resistance. How, from such a graph, would you obtain an estimate of the height reached by the ball?

**2. The attempt at a solution**

I think the graph should be:

Where time is on the X-axis and velocity on the Y-axis. And maximum height: v

^{2}= u

^{2}+ 2as with v = 0. (v = velocity at t, u = velocity at t = 0, s = distance travelled)

But I am not sure about this.
