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

a) a = 3.29 m/s²

b) a = 3.51 m/s²

Explanation:

mass of dogs = 19 kg

loaded sled mass = 210 Kg

a)writing all the forces in x direction

a = 3.29 m/s²

b) acceleration  when sled start to move the friction will now be acting will be kinetic friction.  

a = 3.51 m/s²

false

explanation:

boats, things on boats luggage are way more heavy then water.

are there answer choices to this question? this seems like a question where you have options to choose from.
