A mass m = 17 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.06, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 28° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 28° (thus on the incline it is parallel to the surface) and has a tension T = 34 N.
a) What is the work done by tension before the block gets to the incline?
b) What is the work done by friction as the block slides on the flat horizontal surface?
c) What is the speed of the block right before it begins to travel up the incline?
d) How far up the incline does the block travel before coming to rest?
e) What is the work done by gravity as it comes to rest?

Let's suppose we are pulling a box of mass m along a horizontal
floor. All sides of the box have the same type of surface (same
coefficient of friction between any side and the floor). In one
case, the contact surface is much larger (first picture) and in
another, it is much smaller. Will there be any difference in the
force of friction? Why?

A 91 kg crate, starting from rest, is pulled across a floor with
a constant horizontal force of 340 N . For the first 15m the floor
is frictionless, and for the next 15 m the coefficient of friction
is 0.22.
What is the final speed of the crate?

A solid sphere (mass 0.324 kg, radius 0.245 m) sits at rest on a
horizontal floor. You begin to push the sphere until it is rotating
at 42.6 Hz. Assume the sphere always moves by rolling without
slipping. Find the work you have done to accelerated the sphere, in
J.

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...
