A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!). The dogs have average masses of 19.0 kg, and the

aliina [53]

Answer:

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

$\sum F_x=8F_d-f_{s(max)}= (m_s+8m_d)a\\a=\dfrac{8F_d-\mu_sm_sg}{m_s+8m_d}\\a=\dfrac{8\times 185-(0.14)(210)(9.81)}{210+8(19)}$

a = 3.29 m/s²

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

$a=\dfrac{8F_d-\mu_sm_sg}{m_s+8m_d}\\a=\dfrac{8\times 185-(0.1)(210)(9.81)}{210+8(19)}$

a = 3.51 m/s²
