How much mechanical energy is lost due to friction

Reference no: EM13645813

A crate of mass 10.0 kg is pulled up arough incline with an initial speed of 1.50 m/s. The pulling forceis 100 N parallel to the incline, which makes an angle of16.0° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled5.05 m.
a) How much work is done by gravity?
b) How much mechanical energy is lost due to friction?
c) How much work is done by the 100 Nforce?
d) What is the change in kinetic energy of the crate?
e) What is the speed of the crate after being pulled 5.05 m?
