A crate of mass 13.4 kg is pulled up a rough incline with an initial speed of 1.7G m/s. The pulling force is 117 N parallel to the incline, which makes an angle of 19.2degree with the horizontal. The coefficient of kinetic friction is 0.315 and the crate is pulled a distance of 4.G5 m. The acceleration of gravity is 9.8 m/s2 . How much work is done by gravity? Answer in units of J. How much mechanical energy is lost due to friction? Answer in units of J. How much work is done by the 117 N force? Answer in units of J. What is the change in kinetic energy of the crate? Answer in units of J. What is the speed of the crate after being pulled 4.65 m? Answer in units of m/s.
