A 70-pound object is thrown upward with an initial velocity of 45 ft/s along a plane inclined 25 ° from the horizontal, as shown in Figure. The coefficient of friction between the plane and the object is 0.15. Determine: a) The maximum distance that it will climb on the inclined plane. b) The speed of the object when it returns to the starting point. p/s = ft/s
