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.

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

  • Physics -

    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

  • Physics -

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

  • Physics -

    10=2ma
    m= 5/a
    sorry.
