Mrs. Roberts' class won a day at the bowling alley for their good behavior all year. When they arrived, Anna picked the green ball that weighed 6 lbs, and Amanda picked the yellow ball that
weighed 12 lbs. Amanda was having a hard time getting her ball to roll down the lane. Anna
was doing great! She was pushing her ball hard, and it was going straight down the center. She
even got a strike twice!

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
