A bowling 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)
