A crate of mass 9.8 ko is pulled up a rough incline with an initial speed of 1:52 m/'s. The pulling force is 104 N parallel to the incline, which makes an angle of 19.59 with the horizontal. The coefficient of kinetic friction is 0:400, and the crate is pulled 4:90 m. (a) How much work is done by the gravitational force on the crate? (b) Determine the increase In internal energy of the crate-incline system owing to friction. (c) How much work is done by the 104-N force on the crate? (d) What is the change in kinetic energy of the crate? (e) What is the speed of the crate after being pulled 4.90 m
