A 35 kg trunk is pushed 5.0 m at constant speed up a 30° incline
by a constant horizontal force. The coefficient of kinetic friction
between the trunk and the incline is 0.16. Calculate the work done
by the applied horizontal force. Calculate the work done by the
weight of the trunk. How much energy was dissipated by the
frictional force acting on the trunk? From now suppose the 50 kg
trunk is pushed 5.4 m at constant speed up...

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
friction between the surface and block is 0.35. If the block has an
initial velocity of 3.6 m/s and the force does 200 J of work on the
block, find:
(a) The total distance moved by the block.
(b) The final velocity of the block.

A 65.0 kg box is pushed up a ramp inclined at 27.0∘. The applied
force (F) is horizontal and causes the block to move at a constant
speed. Determine the magnitude of the applied force,
a. when the ramp is frictionless.
b. when the coefficient of kinetic friction is 0.200.

Part 1) A 1.0 kg block is pushed 2.0 m at a constant velocity up
a vertical wall by a constant force applied at an angle of 29.0 ◦
with the horizontal, as shown in the figure. The acceleration of
gravity is 9.81 m/s 2. Drawing not to scale. If the coefficient of
kinetic friction between the block and the wall is 0.20, find a)
the work done by the force on the block. Answer in units of J.
