A 20 kg ball must be moved from the ground to a height of 5 feet. Shown are two possible ways in which the ball might be moved to that height: one by dead-lifting the ball straight up, and the other by pushing the ball up the inclined plane. When the ball is lifted straight up, the ball is moving directly against the vertical force of gravity ( 9.8 ms2 ⋅ mass). When the ball is pushed up the inclined plane, the angle at which it is pushed decreases the amount of gravitational force working on the ball in the direction of the push. The same amount of work is done in both instances, whether the ball is lifted straight up or pushed up at an angle. What amount of acceleration due to gravity is affecting the ball on the inclined plane? Note the following conversion factor: 1 m=3.28 ft
