block 1 of mass m1 slides from rest along a frictionless ramp from height h = 3.2 m and then collides with stationary block 2, which has massm2 = 5m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction ?k is 0.35 and comes to a stop in distance d within that region. What is the value of distance d if the collision is
(a) elastic and
(b) completely inelastic?
