A stone is projected vertically upwards with a velocity of 30m/s from a tower of height 50m negleting air resistance,determine the maximun height it reached from the ground (g=10ms^-1)
It takes 3 seconds for the stone to reach the brightest point ( velocity becomes zero ) Vertical displacement = 1/2 * 10 * 3^2 = 45m Maximum height from ground = 50 + 45 = 95m
