Santas reindeer pull his sled m10 x 103 kilogram on an icy, Ask an Expert

Academics

Santa's reindeer pull his sled (m=1.0 x 10^3 kilogram) on an icy (essentially frictionless), horizontal road.

a) Calculate the work done by the reindeer to accelerate the sled to 12 m/s?

b) Find 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 (coefficient = 0.030, width of field is 75 meter) at a fix speed of 12 m/s

c) Find 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 a constant speed.
