Problem

A ball is released from the edge of a balcony that is

20\,\text{m}

above the ground. Take

g = 9.8\,\text{m\,s}^{-2}

. (i) Calculate the speed of the ball after

2\,\text{s}

of its release. (ii) Find the vertical distance the ball has fallen in these

2\,\text{s}

. (iii) Determine the total time taken by the ball to reach the ground from the balcony.
