2. A small stone is projected vertically upwards from a point O with a speed of 19.6msí1.Modelling the stone as a particle moving freely under gravity,(a) find the greatest height above O reached by the stone,(2) (b) find the length of time for which the stone is more than 14.7 m above O.
I dont understand why v is 19.6 for part b, shouldnt it be 0 when it reaches the maximum height.
Thanks in advance.
