A ball of mass 3.00 kg is attached to a cord of negligible mass.The cord is 2.00 m long and is attached to a fixed point at theother end. The ball is released from rest when the cord ishorizontal. When it is at its lowest point, the ball undergoes anelastic collision with a block of mass 1.50 kg that rests on ahorizontal surface. The coefficient of kinetic friction between theblock and the surface is .100.
a) What is the speed of the block just after the collision?
b) How far does the block move before coming to rest?
