1.	A 2 kg sphere moving horizontally to the right with an initial velocity of 5 m/s strikes the lower end of an 8 kg rigid rod AB. The rod is suspended from a hinge at A and is initially at rest. Knowing that the coefficient o restitution between the rod sphere is 0.80. The velocity of the sphere immediately after the impact is V_(s)=(1)/(x)"ms"^(-1) (lft) where 'x' is
