Step 1

Given that mass of the sled and its rider is M=210kg,

Mass of each dog is m=19kg,

Number of dogs is n=8,

The force exerted by each dogs is f=185N

Step 2

The equation for magnitude of the friction force is. help_outlineImage Transcriptionclosef uN Here, N is the normal force, u is the coeffient for friction (I) fullscreen
Step 3

The equation for the weigh... help_outlineImage TranscriptioncloseW =mg (II) here, m is the mass of the sled with the rider, g is the acceleration due to gravity fullscreen
