A 5.00-kg object placed on a frictionless, horizontal table is connected to a cable that

passes over a pulley and then is fastened to a hangng 9.00-kg object. Find the acceleration of the two objects and the tension in the string.

2. Relevant equations

I am using Net Force = (m2)-1/2(m1)(g)

a = force/total mass

3. The attempt at a solution

I am using Net Force = (m2)-1/2(m1)(g) = (9.00)-1/2(5.00)(9.8) = 63.7N

I used 1/2 of m1 because if the were hanging like on an atwood machine it

would be -m1. Since this is horizontal surface would this be correct?

I then divided the force(63.7N) by Total Mass 14.0-kg to get 4.55m/s2

They both should be travling at the same acceleration, I believe

I'm working on the tension.

Am I starting this right?

Thanks,

Kevin
