can someone help with this pleasee

2} so: dogs. each having a mass of 32 Kg. pull a 325-Kg sled horizontally across the snow with coefcient of kinetic friction of [1.0143 between the sled and the snow. With the help of a FED determine: [6] a] How much force must each dog exert in order to move the sled at a constant velocity? b] If each dog applies a force of 36 N [forward]. what average acceleration does the sled experience? c] One dog becomes lame and must be transported on the sled. With what force must each of the remaining dogs pull to receive an average acceleration of 0.?5 ms2 [forward]
