Students are given a situation in which a cart of mass M0 and length D rolls underneath a device dispensing water. The water passes through a hole in the track except during the time that the cart passes underneath the device. The mass of water that empties into the cart every second is R. The cart’s initial speed before passing beneath the water is v0.
