Calculate what is the change in kinetic energy of the crate

Reference no: EM13658795

A crate of mass 10.0 kilogram is pulled up a rough incline with an initial speed of 1.47 m/s. The pulling force is 93.0 Newton parallel to the incline, which makes an angle of 20.2 degree with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.95 meter.

(a) Determine how much work is done by the gravitational force on the crate?

(b) Calculate the increase in internal energy of the crate-incline system due friction.

(d) Calculate what is the change in kinetic energy of the crate?

(e) Estimate the speed of the crate after being pulled 4.95 m?
