Neglect any losses due Part (b) Calculate the size of the average force in Newtons that you must apply on the tire if you push in a direction parallel to the ramp? See Case Part (c) After a few unsuccessful tries, your friend suggests that you push the tire up the ramp by applying a horizontal force, as shown in Case (2).
