A person pushes horizontally on a 3.2kg block that is on an
incline with an angle of 20 degrees. The coefficient of kinetic
friction between the block and incline is is 0.3 and moves at an
acceleration of 1.3m/s^2. Delta x is 1.9m and initial velocity is
0.5m/s. Find the net work done on box and final velocity of the
block.

Two boxes are stacked, with box B placed on top of box A. If box
A is pushed such that both boxes move with a decreasing speed, is
there any friction on either box?

Kinetic friction on box A and static friction on box B
(c) Kinetic friction on box A and kinetic friction on box B (d)
Static friction on box A and kinetic friction on...

A box is pushed up an incline at a constant speed by a
horizontal force of 30 N. The angle of the incline is 15.4 degrees.
The box has a mass of 3.1 kg and moves a total distance of 2.96 m.
The coefficient of kinetic friction between the box and the ramp is
0.59.
What is the work done by the gravitational force during this
motion? J
What is the work done by the friction force during this motion?...

5. A box is released on a smooth incline, which makes an angle
of 37o with respect to the horizontal.
a) What is the boxs acceleration?
b) The box starts from rest and slides a distance (along the
incline) of 75 cm to the bottom of the ramp. What is the speed of
the box at the bottom?
c) The mass of the box is 100 g. When it gets to the bottom it
compresses a spring with a force...

A sphere of mass M = 5kg and radius R = 0.1m rolls withour
slipping with velocity V = 8.4 m/s toward an incline defined by
angle θ = 10 degrees.
1. Calculate the kinetic energy of the sphere right bfore it
goes up the incline
2. Calculate the height the mass gets up the ramp.
3. Consider a box with the same mass and velocity instead
sliding without friction toward the incline. How does this objects
KE before the...

A 10 kg box slides down a long, frictionless incline of angle
30°. It starts from rest at time t = 0 at the top of the
incline at a height of 18 m above ground.

the ground?
---J
(b) From Newton's laws, find the distance the box travels in 1 s
and its speed at t = 1 s.
---m
---m/s
(c) Find the potential energy and...

A box is sliding down an incline tilted at a 11.8° angle above
horizontal. The box is initially sliding down the incline at a
speed of 1.60 m/s. The coefficient of kinetic friction between the
box and the incline is 0.390. How far does the box slide down the
incline before coming to rest?
A) .736 m
B) 1.03 m
C) .883 m
D) .589 m
E) the box does not stop. it accelerates down the plane.

A 150 gram block is pushed up a ramp set at a 20 degree angle
with respect to the horizontal. Its initial speed is 1.24 m/s as a
result of the push, and it travels 14.0 cm up the incline before
coming to rest. How far would it travel down the ramp before coming
to rest if the push was in the opposite direction but the initial
speed was the same?
