Santa's reindeer pull his sled (m=1.0 x 103 kilogram) on an icy (essentially frictionless), horizontal
road.
a) Compute the work done by the reindeer to accelerate the sled to 12 m/s.
b) Compute how much power is being delivered to the sled if they reach the final speed after 20.4 s?
Assume, they are now crossing a snow covered field (μk = 0.030, width of the field is 75 meter) at a constant speed of 12 m/s.
c) Calculate how much energy will be dissipated by friction?
d) Determine the power being delivered by the reindeer in order to keep the sled moving at constant speed.
