- A crate of mass m = 91 kg rests on a rough surface inclined at an angle of θ = 31° with the horizontal. A massless rope to which a force can be applied parallel to the surface is attached to the crate and leads to the top of the incline. In its present state, there is no tension in the rope and the crate is just ready to slip and start to move down the plane. The coefficient of kinetic friction is given by μk=fμs where μs refers to the coefficient of static friction and f = 0.75 a) With a slightly greater applied force than what is found to be the maximum force the rope can exert parallel to the surface of the plane before the crate begins to move, the crate will slide up the plane. Write an equation for the acceleration of the crate when it begins to slide upwards.

- A mass m = 12 kg is pulled along a horizontal floor with NO friction for a distance d =6.6 m. Then the mass is pulled up an incline that makes an angle θ = 26° with the horizontal and has a coefficient of kinetic friction μk = 0.45. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 26° (thus on the incline it is parallel to the surface) and has a tension T =49 N.
