Question

An 8.2 kg crate is pulled 5.4 m up a 30∘ incline by a rope angled 17 ∘ above the incline. The tension in the rope is 120 N and the crate's coefficient of kinetic friction on the incline is 0.26. How much work is done by tension, by gravity, and by the normal force? What is the increase in the thermal energy of the crate and incline? NV I have figured it out I wasn't thinking normal force was 0

Answer #1

A 7.8 kg crate is pulled 5.4 m up a 30o incline by a
rope angled 19o above the incline. The tension in the
rope is 120 N and the crate's coefficient of kinetic friction on
the incline is 0.24.
a) How much work is done by tension, by gravity, and by the
normal force?
b) What is the increase in thermal energy of the crate and
incline?

an 7.8 kgcrate is pulled 4.5mup a 30∘ incline by a rope angled
18∘above the incline. the tension in the rope is 110 n and the
crate's coefficient of kinetic friction on the incline is 0.23. how

A crate of mass 10.6 kg is pulled up a rough incline with an
initial speed of 1.52 m/s. The pulling force is 94 N parallel to
the incline, which makes an angle of 20.2° with the horizontal. The
coefficient of kinetic friction is 0.400, and the crate is pulled
4.94 m.

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.
What forces are acting
on the crate?
Group of answer choices
Friction, gravity, normal force and tension
Gravity and tension

A crate is placed on an incline. The 30 kg crate starts at rest
and then slides 1.5 m along a 35˝ incline. The coefficient of
kinetic friction between the crate and the incline is uk= 0.50. X
is down the incline and Y is perpendicular to the incline.
Determine the net force acting on the crate, including (Fg, Fn, and
Fk). And what is the final speed of the box.

Block 1 (20 kg) is pulled by a rope from
left to right up a ramp which is inclined
50 degrees from the horizontal. The rope pulls on
block 1 with a force of 300 N parallel to the
surface of the inclined plane. The coefficient of kinetic
friction between the block and the surface equals
0.1.
On a sheet of paper, draw the free body diagram
for block 1 using the two-subscript notation from class. Assume
that the...
