Q. A 4.00 kg block is free from rest 2.0m high at the top of a 30 degree frictionless incline. The block makes a head-on elastic collision with another 3.00 kg block initially at rest on a horizontal surface at the bottom of the incline. If the coefficient of friction between the horizontal surface and the second block is 0.30, how far would the second block go on the ground?
