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

In your answer specify the type of friction involved and how it acts in a detrimental manner.arrow_forwardTo determine the coefficients of friction between rubber and various surfaces, a student uses a rubber eraser and an incline. In one experiment, the eraser begins to slip down the incline when the angle of inclination is 36.0 and then moves down the incline with constant speed when the angle is reduced to 30.0. From these data, determine the coefficients of static and kinetic friction for this experiment.arrow_forward

The surfaces must be in contact with each other in order to have friction. The surfaces must be moving against each other in order to have friction.
