The kinetic coefficients of friction between the 5-kg crates A and B and the inclined surface are 0.1 and 0.4, respectively. The coefficient of restitution between the crates is e = 0.8. If the crates are released from rest in the positions shown, what are the magnitudes of their velocities immediately after they collide? The crates are placed upon a 60 degree incline with A above B and the initial distance between them is 0.1m
