With a frictionless, horizontal table, mass 3.60 kg collides head-on with a 9.80-kg block which is initially at rest. The incoming block moves to the right at a velocity of +2.58 m/s. (a) Assume that the collision is perfectly inelastic. Find the final velocities of the two balls, respectively. Determine the loss in the total kinetic energy in the collision.
