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?
