A cart of mass 1.4 Kg is temporarily held stationary on an incline at 9.5 degrees to horizontal. A mass of .16 Kg is attached to the cart by a string over a pulley located at the bottom of the incline; the mass hangs freely from the string. when the cart is released from rest, it accelerates through a distance of 3 meters. Assuming no friction or other dissiptive forces:

How much work does gravity do on the cart?

Using the definition of KE, determne the velocity attained by the cart.
