A.) We start with some review problems A crate of mass 49.6 kg rests on a level surface, with a coefficient of kinetic friction 0.161. You push on the crate with an applied force of 345 N. What is the magnitude of the crate s acceleration as it slides?

B.) You place a crate of mass 37.4 kg on a frictionless 2.91-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.26 s after you released it. What is the angle of the incline?

C.) This time we have a crate of mass 38.7 kg on an inclined surface, with a coefficient of kinetic friction 0.249. Instead of pushing on the crate, you let it slide down due to gravity. What must the angle of the incline be, in order for the crate to slide with an acceleration of 7.86 m/s^2?

A crate of mass 100.0 kg rests on a rough surface inclined at an angle of...

A crate of mass 100.0 kg rests on a rough surface inclined at an angle of 37.0° 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, the crate is just ready to slip and start to move down the plane. The coefficient of friction is 80% of that for the static case a. What is the...

A 336-kg crate rests on a surface that is inclined above the horizontal at an angle of 17.2°. A horizontal force (magnitude = 405 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate and the incline?

A sled and rider have a total mass of 49.6 kg. They are on a snowy hill accelerating at 0.8g. The coefficient of kinetic friction between the sled and the snow is 0.22. What is the angle of the hill's slope measured upward from the horizontal? You may find a spreadsheet program helpful in answering this question.

A mass of 8 kg rests on a floor with a coefficient of static friction of 0.88 and coefficient kinetic friction of 0.33. One force is applied vertically downward of 28 Newtons and another force is applied at an angle of 26 degrees below the horizontal. Calculate what the magnitude this force needs to be in order to begin to move the mass. If that force is removed and another force is applied at an angle of 26 degrees above...

**A crate with a mass of 45 kg is suspended from a massless rope that runs vertically upward over a light pulley. The other end of the rope is connected to a 35 kg crate, which lies on a tabletop. The coefficients of the kinetic friction and the static friction between the crate and the surface are 0.3 and 0.5 respectively. An applied force, F, pulls the 35 kg crate to the right. In the first case, the applied force...
