Angular Acceleration and Velocity..please help :) hi could someone please explain to me conceptually what angular acceleration and angular velocity are. Also how would the angular acceleration and angular velocity of the people on a merry go round change with the location of the people...

you have to assume that there is a rope because the problem says that bricks are PULLED up.

Tension is a force that usually exists in rope when the rope is being stretched. For example, if I were to push a box up an incline, I would be exerting a force on the box. If I were to use a rope to pull a box up an incline, there would be a force pulling the box up and that force is called...

I think you're confusing Fsmax with force due to tension. The force of static friction = \muFn To approach this sort of problem, ALWAYS start off with a free body diagram. I actually just started using these physics forums so I don't know how to draw one on this site but i'll try to...
