Question 30

A stone is thrown with speed U ms−1U \text{ ms}^{-1}U ms−1 from a point A A\,A on top of a sea cliff, 30 m above the water. The stone is projected at an angle of 45∘ 45^\circ\,45∘ to the horizontal. Point B B\,B represents the highest point in the stone's path, which is 20 m above the level of the cliff.

a.

Find the value of UUU.

[3]
b.

Find the horizontal distance travelled by the stone from A A\,A to the water.

[6]
c.
