Lifting yourself.A man stands on a platform as shown in the figure below, and pulls up

on a rope that winds through a frictionless pulley attached to the platform. The other end

of the rope is attached to the ceiling. The mass of the man is m, and the combined mass of

the platform and pulley is M.Can the man lift the platform off the ground if he pulls hard

enough? If so, find the minimum tension required to give the platform a positive (upward)

acceleration, thus lifting it off the floor.

2. Relevant equations

M = Pulley and Platform total mass

m = Mass of the man

3. The attempt at a solution

Well in class i didn't learn that about tension on a pulley system. But I believe the only forces acting on this is the total weight(m + M), Tension, and Gravity

so i was thinking the equation would loo something like T - Ft = ma?

Im not to sure about my equation, but i was wondering if someone would help me out with this problem

Thanks!
