What is the change in kinetic energy for the block

Reference no: EM13646104

A crate of mass 10.0 kg is pulled up a rough incline with aninitial speed of 1.50 m/s. The pulling force is 100.0 Nparallel to the incline, which makes a 20.0 degree angle with thehorizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.00 meters.
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 N force?
d) What is the change in kinetic energy for the block?
e) What is the speed of the crate after being pulled 5.00m?
