Question

Cart moving down an inclined ramp.Let the gravitational potential energy be defined to be zero when the cart is at the bottom of the ramp. Write an expression for the gravitational potential energy of the cart in terms of its mass, the distance along the inclined ramp x, and the angle of the ramp. How will the kinetic energy, gravitational potential energy, and the total mechanical energy change as the cart rolls down the inclined ramp (for each type of energy, answer if it decreases, increases, or stays the same)?
