Box A, which weighs 47 lb, is released from rest in the position shown in the top figure, where h = 3 ft. The box slides down the fixed incline with negligible friction and it lands on a cart B, which is initially at rest and weighs 12 lb. When A reaches the bottom of the incline, the velocity of A is completely horizontal and A starts sliding on the cart. The coefficient of kinetic friction between A and B is μk = 0.6.

Determine the distance d from the right end of the cart at which the box A stops relative to the cart.
