so I can use the two equations to find the missing variables? what does that have to do with max height?

I'm down for helping me get to the solution, but you are being ridiculous.

Having an initial velocity. Please stop trying to raise your post count and provide a reasonable solution. I'm just trying to refresh myself on the subject and this was a problem I wasn't positive about.

because gravity is acting in the direction toward the ground...

i'm not sure. gravity?

Would I have to cut t (2s) in half?

the max height? I'm not sure.

the max height

I think it is assumed he started at 0 then went to 0 during the swing so he traveled to the other side of the circle (8 total)? that's really all the information provided. how would you find velocity if you had distance?

no there is no diagram. Although after reading a bit i believe I need to use the centripetal force at least for the lowest point on the rope swing. (which I guess should be the max tension area?) so T-mg=m*(v^2/r) ... but how do I find the velocity?

Yes that is the whole problem. I believe the professor is saying it is a pendulum maybe? this is from a test the professor gave out last year.
