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-Ff=m*a
F=m*a+Ff
F=210*0.13+0.095*210*9.81
F= 223.0095 N
