A snowmobile is pulling a sled (m = 375 kg) across the snowy tundra (Fig. P9.79). The snowmobile applies a pulling force of 2511 N at an angle of 15o with respect to the ground and pulls the sled over a distance of 50.0m.
(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?
