In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2
A ball is thrown vertically upwards with speed 12.6 m s−1^{-1}−1 from a point 2 metres above horizontal ground.
The ball is modelled as a particle moving freely under gravity.
Using the model, find the time between the ball being thrown and the ball hitting the ground.
Find the speed of the ball as it hits the ground.
