In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2
A man stands on a ledge and throws a ball into the air.
At the instant the ball leaves his hand, the ball is 4 metres above the ground and is moving vertically upwards with speed 8 m s−1^{-1}−1.
The ball is modelled as a particle moving freely under gravity.
The ball hits the ground T T\,T seconds after leaving the man's hand.
Using the model, find the value of TTT.
