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.
Find the time taken for the stone to reach the ground.
Find the horizontal distance travelled by the stone before it reaches the ground.
