A smooth spherical ball of mass M = 2 kg is resting on two identical blocks A and B as shown in the figure. The blocks are moved apart with same horizontal velocity V = 1 m/s in opposite directions (see figure). (a) Find the normal force applied by each of the blocks on the sphere at the instant separation between the blocks is a = sqrt2R, R = 1.0 m being the radius of the ball. (b) How much force must be applied on each of the two blocks (when a = sqrt2R) so that they do not have any acceleration. Assume that the he horizontal surface is smooth.

1.	A smooth spherical ball of mass M = 2 kg is resting on two identical blocks A and B as shown in the figure. The blocks are moved apart with same horizontal velocity V = 1 m/s in opposite directions (see figure). (a) Find the normal force applied by each of the blocks on the sphere at the instant separation between the blocks is a = sqrt2R, R = 1.0 m being the radius of the ball. (b) How much force must be applied on each of the two blocks (when a = sqrt2R) so that they do not have any acceleration. Assume that the he horizontal surface is smooth.
