In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2
A ball is thrown vertically upwards with speed 14 m s−1^{-1}−1 from a point 1.5 metres above horizontal ground.
The ball is modelled as a particle moving freely under gravity.
Using the model, find the maximum height above the ground reached by the ball.
State one modelling assumption you have made in part (a).
State how the maximum height would change if the modelling assumption in part (b) were not made.
