A package of mass 5.30 slides a distance 1.41 down a long ramp that is inclined at an
angle12.3 below the horizontal. The coefficient of
kineticfriction between the package and the ramp is = 0.315
.
A ) Calculate the work done on the package by friction.
B) Calculate the work done on the package by gravity.
C) Calculate the work done on the package by the
normalforce.
D) Calculate the total work done on the package.
E) If the package has a speed of 2.25 at the top of the ramp, what is its speed after
slidingthe distance 1.41
down the ramp?
