In the figure, block 1 of mass m slides from rest along a frictionless ramp from height h = 2.7 m and then collides with stationary block 2, which has mass m = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction k is 0.1 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? h Frictionless -k 9 (a) Number Unit (b) Number i Unit
