Nicole lifts a bowling ball with a mass of 6.2 kg to a height of 1.5 meters above the floor. (a) How much work does she do to lift it? [be careful! E-S-AJ (b) How much gravitational potential energy (GPE) does the ball now have relative to the floor? (E-S-AJ (c) Work put into lifting an object to a given height is (greater than, less than, equal to) the GPE of the object as it rests at that height. (d) How much kinetic energy (KE) does the ball have as she holds it at rest at this height? while increasing in (height. (e) If she drops the ball, the ball will decrease in (height, speed) This indicates a transference of (KE, GPE) to (KE, GPE) speed)
