3. A box with a mass of 15.0 kg moves on a ramp inclined at an angle of 47.5° above the horizontal. The coefficient of kinetic friction between the box and the ramp surface is H = 0.300. Calculate the magnitude of the acceleration of the box if you push on the box with a constant force F= 147.0N that is parallel to the ramp surface and directed down the ramp, moving the box the box up the ramp. a. Draw the free-body diagram of the truck b. Magnitude of the average net force acting on the truck.
