A ballon, carrying a small uniform ball, starts from rest from a point on the ground at time 1 = 0 and moves vertically upwards with uniform acceleration, where f<g. At time t = T, the ball gets gently detached from the balloon and moves under gravity, Sketch the velocity - time graph for the upward motion of the ball, from t = 0 until the ball reaches its maximum height. Find the
maximum height reached by the ball in terms of T, f and g.
