Please show work for each part.
A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

A stockroom worker pushes a box with mass 11.9 kg on a horizontal surface with a constant speed of 3.40 m/s . The coefIficient of kinetic friction between the box and the surface is 0.17. What horizontal force must the worker apply to maintain the motion? If the force calculated in the previous part is removed, how far does the box slide before coming to rest?
A storeho use worker pushes a box with a refrigerator (mass:96.0-kg) at constant velocity for a distance of 11.0 m. He pushes in the direction parallel to the horizontal floor. A 250.0-N friction...
A storeho use worker pushes a box with a refrigerator (mass:96.0-kg) at constant velocity for a distance of 11.0 m. He pushes in the direction parallel to the horizontal floor. A 250.0-N frictional force opposes the motion of the box. Use Newtons second law and definition of work to answer the questions below. (a) (1 point) What is the acceleration of the box? as (b) (2 points) What is the net force, acting on the box? Write down Newtons second...
