Question

Pete slides a crate up a ramp with constant speed at an angle of 21.3 ◦ by exerting a 256 N force parallel to the ramp. How much work has been done against gravity when the crate is raised a vertical distance of 2.3 m? The coefficient of friction is 0.232. Answer in units of J.

Answer #1

A worker pushes a 27.0kg crate a distance 9.50m along a level
floor at constant speed by exerting a pushing force on the crate
which is directed 35.0◦ below the horizontal. The coefficient of
kinetic friction is 0.230. (a) How much work did the worker do on
the crate? Now the worker pushes the same crate up a 35.0◦ incline
at constant speed, with the same kinetic friction coefficient. This
time the worker pushes horizontally on the crate. Over the...

You are pulling a
heavy crate (mass m) up a ramp inclined at an angle
θ to the horizontal. The ramp is not a smooth
surface. The rope that you are pulling with is parallel to the
incline.

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.

A construction worker pushes on a 10 kg crate down an inclined
plane that is 7.0 m long and is inclined at an angle of 20 degrees
to the horizontal. As a result, the crate slides down the entire
length of the plane with a constant speed of 3.0 m/s. Suppose that
the worker pushes directly on the crate in a direction parallel to
the incline with a force of 50 N for the entire length of the
plane. A)...
