## Homework Statement

Sled dog to pull on a snowy sleigh horizontal road, the mass of its load is 210 kg. Snow and sleigh runners movement between the friction coefficient is 0.095. Dogs sleigh force exerted by the horizontal. acceleration of 0.13 m/s2? Gravitational acceleration is 9.81 m/s2.

## Homework Equations

How much force as the dogs pull the sled

## The Attempt at a Solution

newton second law and by projection:

F-F

_{f}=m*a

F=m*a+F

_{f}

F=210*0.13+0.095*210*9.81

F= 223.0095 N
