"A 10.0 kg box is held at the top of a 12.0 m long delivery ramp that makes a 17.0 degree angle with the horizontal. When the box is released, it slides down the ramp, with a constant 20.0 N frictional force exerted on it over the full 12.0 m . What kinetic energy does the box have at the bottom of the ramp

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?
