At the end of a downhill run, a skier of mass slides up a rough slope at an angle of to the horizontal, to slow down. He arrives at the upward slope with an initial speed of The coefficient of friction between the skier and the slope is Find how far up the slope he comes to rest, and show that he remains at rest there without falling back down the slope.

Important Questions on Friction
A book of mass is at rest on a rough slope at an angle of to the horizontal. It takes a force of parallel to the slope to break equilibrium and drag it up the slope.
Find the coefficient of friction between the slope and the book.

A book of mass is at rest on a rough slope at an angle of to the horizontal. It takes a force of parallel to the slope to break equilibrium and drag it up the slope.
Find the acceleration of the book down the slope if the force is applied down the slope.

A box of mass is at rest on a rough slope at an angle of to the horizontal. The coefficient of friction between the slope and the box is
Find the force it takes parallel to the upwards slope to break equilibrium and drag the box up the slope.

A box of mass is at rest on a rough slope at an angle of to the horizontal. The coefficient of friction between the slope and the box is
If the force were applied down the slope and parallel to it, find the acceleration.
