If you lift the ball with a force of 100N, the ball’s acceleration is “2a” The weight of the ball is 78N. What is the acceleration of the bowling ball?
you lift a bowling ball with a force of 89N and the ball accelerates upward with an acceleration of “a”?

The mass of the bowling ball is:
m = (mg)/g = W/g = (78 N)/(9.81 m/s^2) = 7.95 kg
The net force on the bowling ball is:
F(net) = F – W = (89 N) – (78 N) = 11 N
So, the acceleration is:
a = F(net)/m = (11 N)/(7.95 kg) = 1.38 m/s^2
