Question

A ball projected vertically upwards from ground with velocity v=24m/s. Assume the air resis†an ce produces a cons†an t retardation of 2m/s^2. Then (g=10m/s^2) 1. The maximum height attained is 28.8m 2. Time of ascent is more than time of descent 3. Time of descent is more than time of ascent 4. velocity of the particle just before it hits the ground is 8\sqrt6
