While leaning out a window that is 6.3 m above the ground, you drop a 0.60 kg basketball to a friend at ground level. Your friend catches the ball at a height of 1.0 m above the ground. Determine the following(a) the amount of work done (in J) by the force of gravity on the ballJ(b) the gravitational potential energy (in J) of the ball-earth system, relative to the ground when it is releasedJ(c) the gravitational potential energy (in J) of the ball-earth system, relative to the ground when it is caughtJ(d) the ratio of the change (PEF - PE) in the gravitational potential energy of the ball-earth system to the work done on the ball by the force of gravityAPE/W=
