part one:
a crate is pulled by a force (parallel to the
incline) up a rough incline. the crate has an
initial speed shown in the figure below. the
crate is pulled a distance of 5.59 m on the
incline by a 150 n force.
the acceleration of gravity is 9.8 m/s^2
a) what is the change in kinetic energy of
the crate?
answer in units of j.

part two:
b.)what is the speed of the crate after it is
pulled the 5.59 m?
answer in units of m/s.
