Question

A pack of dogs are pulling a wooden sled and rider of combined mass

of 238 kg across dry snow. How much force do the dogs need to apply
to cause the sled to begin to move?

Answer 1

FN=-Fg -> Fg=mg -> Fg = 238 kg*9.8 m/s^2 ->

Fg = -2432.4 so FN = 2432.4 -> FF = μs*FN ->

FF = 0.22*2332.4 N -> FF = 513.128 ->

Fapplied > 513.128 N
