Question 7

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A stone is thrown horizontally with speed 12 m s−1^{-1}−1 from the top of a cliff, 45 m above horizontal ground.

The stone is modelled as a particle moving freely under gravity, and air resistance is modelled as negligible.

a.

Find the time taken for the stone to reach the ground.

[2]
b.

Find the horizontal distance travelled by the stone before it reaches the ground.
