Question

A box with mass m = 1.2kg on an inclined frictionless surface is
released from rest from a height *h* = 1.35 m . After
reaching the bottom of the incline the box slides with friction
(μk=0.2) along a horizontal surface until coming to a rest after a
distance *d*.

1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names.

2. Draw a free body diagram for the box while it is on the horizontal surface. Clearly label all forces with standard names.

3. What is the kinetic energy of the box at the bottom of the incline?

4. Calculate the distance d the box will travel on the horizontal surface before coming to a rest.

5. How much is the total work done by the frictional force on the box? Explain conceptually why the work is positive or negative.

A box with mass m =
1.2kg on an inclined frictionless surface is released from rest
from a height h = 1.75 m . After reaching the bottom of
the incline the box slides with friction ( μ k = 0.25 ) along a
horizontal surface until coming to a rest after a distance
d.

diagram for the box while it is...

A 12.0-kg box is released from the top
of an incline that is 5.00 m long and makes an angle of
40.0o to the horizontal ground. A 60.0-N friction force
is acted on the box to impede the motion of the box.

A block with a mass of 2.5kg lies on a surface that is inclined
at an angle of, θ=22o, with the horizontal. The coefficient of
friction between the block and the surface of the incline is,
uk=0.20.
a) Apply Newton’s 2nd Law to determine the acceleration of the
block as it slides down the
surface. Answer
--> [±1.9m/s2]
b) Determine the magnitude of the velocity of the block at the
base of the inclined surface
if the block starts from rest...

A 9.31 kg block is placed at the top of a frictionless inclined
plane angled at 14.9 degrees relative to the horizontal. When
released (from rest), the block slides down the full 2.77 meter
length of the incline. Calculate the speed (magnitude of the
velocity) of the block at the bottom of the incline. [Start by
drawing a free-body diagram for the block.] Note that all the
information provided may not be necessary to solve the problem.

As shown in Figure 1, a block (mass: 2.4 kg) is initially at
rest near the top of an inclined plane, oriented at a 25° angle
above the horizontal. The coefficients of static and kinetic
friction along the incline are 0.2 and 0.1, respectively.
(a) Just after the block is released from rest, draw a free-body
diagram for it. (Assume that the block is moving after being
released from rest.)
(b) Determine the magnitude of the normal force acting on...

A box, initially at rest, is pulled by a rope as it slides along
a horizontal (level) carpeted floor in the positive direction;
there is friction. The mass of the box is 8 kg and the tension in
the rope has a magnitude of 40 N. After 4 seconds of pulling, the
box has a speed of 12 m/s.
1. While the box is being pulled:
a. what is the magnitude of acceleration of the box? Answer:
_________
b. what...

A block of ice, released from rest at the top of a 1.50-m-long
ramp, slides downhill, reaching a speed of 2.50 m/s at the bottom.
If the coefficient of kinetic friction μ=0.3 what is the angle
between the ramp and the horizontal? please include free-body
diagram.

A 4.08 kg box begins to slide from rest through a plane inclined
