Starting from rest, a 28.4 kg child rides a 9.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.4 m/s. If the slope makes an angle of 15.9° with respect to the horizontal, how far along the hill did she slide on her sled? distance = m
A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass ma and makes his way over the ledge (see the figure). If the coefficient of maximum static friction between the rock and the ground is µ, and the mass of the hiker is mâ, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. mc = Ju
