A box can be moved up an inclined plane with constant velocity by a force of magnitude F1 or down the inclined plane with constant velocity by a force of magnitude F2.
Find the coefficient of kinetic friction μk between the box and the inclined plane given that F1 = 10F2 and both forces are parallel with the inclined plane.
The angle θ between the inclined plane and the horizontal plane is 16°.

A student pushes a block at the bottom of a ramp that makes an angle 34° with the horizontal. (as shown)
The block is given an initial speed vo = 1.7 m/s up the ramp.
There is a kinetic friction between the ramp and the block μ=0.24 as it slides some distance up the ramp before is slides back down.
How far (in meters) along the ramp will the block slide before it starts sliding down ?

The 310N crate is initially stationary on a ramp that makes an angle of 26° with the horizontal.
The coefficients of friction between the crate and the inclined surface are µs = 0.78 and µk = 0.18.
Determine the acceleration of the crate if the horizontal force F = 381N .
