Question 51

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

A ball is projected vertically upwards from ground level with speed 20 m s−1^{-1}−1.

The ball is modelled as a particle moving freely under gravity.

a.

Using the model, find the maximum height above the ground reached by the ball.

[2]
b.

When the experiment is carried out, the ball is observed to reach a maximum height of only 17.2 metres. Explain, by referring to the modelling assumptions, why the model gives too large an answer.
