He stops to rest at the middle of the rope. The rope will break if the tension in it exceeds 3.00 x 10⁴N, and our heros mass is 81.6 kg.

b. What is the smallest value the angle can have if the rope is not to break?
Two blocks are connected via a massless frictionless pully system. The hanging block is 3 kg. The other block is on a ramp of 25◦ and has a mass m. The coefficients of friction between the block on the ramp and the ramp are: µs = .8 and µk = .5.
a. What is the minimum mass m that will not slip?
b. If the minimum mass is nudged, it will start being pulled up the incline. What will the acceleration be when that happens?
