A ball of mass 0.1kg is thrown vertically upwards with a speed of 10ms-1 from the top of a tower 10m high. Neglecting air resistance, its total energy just before hitting the ground is(take g = 10ms-2)
Answer Details
Height h = 1/2 (U2/g) = 102/20 = 5m
Energy before hitting ground is = P.E at the height of 15m.
