Problem
A stone is projected vertically downward from the top of a 100m high tower with an initial speed of 10m/s. Air resistance may be neglected.
(i) Taking downward direction as positive, write the equation of motion for the stone, clearly indicating the sign of each term.
(ii) Find the time taken by the stone to reach the ground.
(iii) Compute its speed on reaching the ground.
