Abowling ball with a mass of 4.5 kg travels at a velocity of 37 m/s for 2.5 s until it stopped at the end of the lane by the ball return. what additional info is required to determine the weight of the bowling ball?

None. We already have more than we need ... provided only that the lane is on Earth.

Weight = (mass) (gravity).

On Earth, 'gravity' = 9.8 m/s^2.

Weight of the ball =

(4.5 kg) (9.8 m/s^2).= 44.1 newtons.

(roughly 9.9 pounds)

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
