A ball of mass .1kg is dropped from a height =11m above the surface of a triangular block of massM=1Kg. The triangular block is at rest on frictionless table and the kinetic energy is conserved during the collision. suppose the ball moves horizontally immediately after it hits the block. Find the speed of the block after collision?
