A 12.0-kg package in a mail-sorting room slides 2.00 m down a
chute that is inclined at 53.0∘53.0∘ below the horizontal. The
coefficient of kinetic friction between the package and the chute’s
surface is 0.40.
I know hot to calculate Work for each separate force on the
package. But how would you use the Work Kinetic Energy
Theorem to find the package's change in kinetic
energy?
Thanks!

A block of mass m = 2.1 kg slides down a 36 ° inclined ramp that
has a height h = 3.1 m. At the bottom, it hits a block of mass M =
7.1 kg that is at rest on a horizontal surface. Assume a smooth
transition at the bottom of the ramp. If the collision is elastic
and friction can be ignored, determine the distance the mass m will
travel up the ramp after the collision.

A 50 kg crate slides down a ramp that is inclined by 30 degrees
from the horizontal. The acceleration of the crate parallel to the
surface of the ramp is 2.0m/s^2, and the length of the ramp is
10m.
Determine the kinetic energy accumulated by the crate when it
reaches the bottom of the ramp if it started from rest at the top
of the incline.
Calculate the amount of energy lost by the crate due to friction
in its...

A block with mass m = 17.2 kg slides down an inclined plane of
slope angle 13.8o with a constant velocity. It is then
projected up the same plane with an initial speed 4.05 m/s. How far
up the incline will the block move before coming to rest?

A crate of mass 50.0 kg slides down a 60.0o incline.
The crates acceleration is 4.00 m/s2, and the incline is
10.0 meter long. a) What is the kinetic energy of the crate as it
reaches the bottom of the incline? b) How much work is spent in
overcoming friction? c) What is the magnitude of friction force
that acts on the crate as it slides down the incline?

The diagram shows a mass after it slides down the inclined
plane. There is a static
friction coefficient of 0.5 and a kinetic friction coefficient of
0.3 between the box
and the incline. The angle of the incline is 30 degrees , and the
box has a mass of 4
kg . The starting height at the top of the ramp is 0.8 meters (and
the distance along
the ramp is 1.6 meters ).
A) Prove, with numbers, that the...

8. A cart slides down an inclined plane with the angle of the
incline θ starting from rest. At the moment the cart begins to
move, a ball is launched from the cart perpendicularly to the
incline.
(a) Choosing an x-y-coordinate system with the x-axis along the
incline and the origin at the initial location of the cart, derive
the equation of the trajectory that the ball assumes from the
perspective of this coordinate system.
(b) Determine where the maximum...

A box of physics books slides down a ramp inclined at an angle
of 40 degrees to the horizontal. The total length of the ramp is
10m. The coefficient of kinetic friction between the box and the
ramp is .2 for the top 8m and zero for the bottom 2m. Upon reaching
the bottom of the ramp, a spring bounces the box back upward.
(a) Find the distance that the box travels back up the ramp on
the return bounce....
