4. A heavy frictionless cart rolls down an incline. A string is attached to the cart, looped over a pulley and connected to a box on a level surface. The cart has a mass of 10.5 kg and the box has a mass of 6.50 kg. The incline makes an angle of 21.0° above horizontal. If the coefficient of friction between the box and the surface is just 0.085, what is the acceleration of the box? (Include Force diagrams with your answers.) 21.00
