A team of eight dogs pulls a sled with waxed wood runners on wet snow. The dogs have average masses of 16.5kg, and the loaded sled with its riders has a mass of 202kg. The coefficient of static and kinetic friction is .14 and .1

a. Calculate the acceleration starting from rest if each dog exerts an average force of 150N backward on the snow in m/s^2.

b. What is the acceleration once the sled starts to move in m/s^2?

c. Using part (a), calculate the force in the coupling between the dogs and the sled in newtons.

d. Using part (b), calculate the force in the coupling between the dogs and the sled in newtons.

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...
