When you lift a ball with a force of 82N, the ball accelerates upward with an acceleration of a. If you lift with a force of 92N, the balls acceleration is 2*a.
Find the weight of the ball, and the acceleration a.

I know that
82 = ma +mg
92 = m2a + mg

That logic is correct right? just dont know how to figure out m or a :(
