Question 36

A stone is thrown from a point $O\,$ on horizontal ground with velocity $k(5i+j)ms−1k(5\mathbf{i} + \mathbf{j})\text{ms}^{-1}$ , where $k\,$ is a constant. The maximum height of the stone above the ground is 5 m.

a.

Find the exact value of $k$ .

[3]

b.

Find the horizontal distance from $O\,$ to the point where the stone returns to the ground.
