Question

1. A dog team pulls a sled with a total mass of 220 kg. The coefficient of kinetic friction between the sled and the snow is 0.08. The sled accelerates at 0.75 m/s^2 until it reaches a cruising speed of 12 km/hr.

a) What power does the team have to produce during the cruising phase (after the acceleration phase)?

b) What is the average power output the team has to produce during the acceleration phase (You will need to use some kinematics here)?

Answer 1

Thanks
