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 2a. Find the weight of the ball, and the acceleration a.

Question

I tried solving this via substitution algebra, but the answer still didn't work, PLEASE help!!!!

Answer 1

force=m(a+g)
force1=m(a1+g)

force1-force=m(a1-a)
10N=ma)
m=10/a
and theweight then is mg or 10g/a

Answer 2

I think the 2a is meant to be 2 * a

Answer 3

10=2ma
m= 5/a
sorry.
