3) A sphere of radius 20 cm is placed at point A on an inclined plane, as shown in the diagram below. It isreleased from rest and rolls without slipping down the plane in a straight line. If it can just reach point B,which is the highest point on the vertical circle of radius R = 1.0 m, determine the height of point A.(Given that the moment of inertia of a sphere of mass m, radius r about an axis through its centre ismr².)
