Calculate how much work is done by gravity

Reference no: EM13490419

A crate of mass 14.0 kg is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100 N parallel to the incline, which makes an angle of 19.0° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.20 m. How much work is done by gravity?
