If the force is applied in the direction of motion, the power required to pull a dog sled across the snow can be computed from: P = (force)(speed) = FV. If the force due to friction on a sled is 250 N, how much horsepower must the dogs provide to pull the sled at 5 m/s?

power required to pull the sledge p = F*v = 250*5 = 2500 watt = 2.5 kw

1 HP = 0.7457 KW
