Determine the change in kinetic energy of the crate

Reference no: EM13340589

A crate of mass 9.8 kg is pulled up a rough incline with an initial speed of 1.56 m/s. The pulling force is 102 N parallel to the incline, which makes an angle of 20.2° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.98 m.
