An 8.5-kg block is pushed along a horizontal rough surface by a
40-N force inclined at 20° with the horizontal. The coefficient of

A person pulls a 50-kg crate over a displacement of 40-m along a
horizontal floor with a rope of 100N tension. The rope makes an
angle of 37o with the horizontal surface. The floor is rough,

A rope that is directed 30° above the horizontal, is exerting a
10.0-N force to pull a 5.0-kg block at constant speed along a 5.0-m
horizontal floor. After drawing the free-body diagram find:

the work done by the rope's force
the increase in the thermal energy of the block-floor system
the coefficient of kinetic friction between the block and
floor.

A horizontal force of magnitude 32.5 N pushes a block of mass
4.05 kg a distance of 3.00 m across a floor, where the coefficient
of kinetic friction is 0.600.

block-floor system?
(b) During that displacement, the thermal energy of the block
increases by 36.0 J. What is the increase in thermal energy of the
floor?

A horizontal force of 60.0 N is applied to a 3.00 kg block as
the block slides a distance of 0.500 m up a ramp. The ramp is
inclined at an angle of 30.0◦ and the coefficient of kinetic
friction between the ramp and the block is 0.600. If the block is
initially at rest, how fast is it moving at the end of the
displacement? Please make answer very detailed
