Problem 5: Parabolic Fall (3 points) A spherical ball of radius

Problem 5: Parabolic Fall (3 points) A spherical ball of radius r = 0.04 m rests exactly on the rightmost end of a horizontal platform. The ball is given a quick push that causes it to instantaneously acquire speed u towards the right. The subsequent trajectory of the ball's falling motion traces a perfect parabola if and only if u > Umin- Find Umin- Neglect friction and air resistance. Leave your answer to 2 significant figures in units of m s-1
