Question 40

A particle $Q\,$ is projected with speed $\text{ ms}^{-1}$ from a point $A$ , 30 m above the ground. $Q\,$ is projected at an angle of $45^\circ\,$ to the horizontal. $B\,$ is the greatest height reached by $Q$ , 15 m above $A$ .

a.

Find the value of $U$ .

[3]

b.

Find the horizontal distance travelled.

[4]

c.
