If you lift a bowling ball with a force of 82 N, the ball accelerates upward with an acceleration a. If you use a force of 92 N, the ball is accelerating 2a lift. Find the weight of the bowling ball.
How do you find the weight of the bowling ball thx?

m is the mass of the ball, and mg is the weight
F = ma
but this force is the net, after the static weight is subtracted
(82–mg) = ma
(92–mg) = 2ma
(1/2)(92–mg) = ma
(1/2)(92–mg) = (82–mg)
46 – mg/2 = 82 – mg
mg – (mg/2) = 82 – 46
mg/2 = 36
mg = 72 Newtons, the weight
m = 72/9.8 = 7.3 kg, the mass
