A snowmobile is pulling a sled (m=375 kg) across the snowy tundra. The snowmobile applies a pulling force of 2511 N. at an angle of 15° with respect to the ground and pulls the sled over a distance of 50.0 m.
(a) How much work is done by the snowmobile?
(b) If the sled is also being acted on by a constant kinetic friction force of 255 N and it started from rest, what is the final speed of the sled?
