Ateam of eight dogs pulls a sled with waxed wood runners on wet snow ( the dogs have average masses of 19.0 kg, and the loaded sled with its rider has a mass of 210 kg.
(a) calculate the acceleration starting from rest if each dog exerts an average force of 185 n backward on the snow.
(b) what is the acceleration once the sled starts to move?
the coefficient of kinetic friction is 0.1 and static friction is 0.14
