Problem
A 1.2kg block slides at 4.0m/s on a horizontal surface and collides head-on with a 0.80kg block that is initially at rest on the same surface. The blocks stick together on impact. The coefficient of kinetic friction between the combined block and the surface is 0.15.
(a) Determine the speed of the combined block immediately after the collision.
(b) Calculate the distance the combined block slides before coming to rest.
