A53.0 kg sled is sliding on snow with μk=0.110. how much friction force does it feel?

57.1 N

Explanation:

The force of friction experienced by the sled is given by:

where

is the coefficient of friction

N is the normal reaction exerted by the snow on the sled

For a flat surface, the normal reaction is equal to the weight of the object:

N = mg

where

m = 53.0 kg is the mass of the sled

g = 9.8 m/s^2 is the acceleration of gravity

Substituting the second equation into the first one, we find:

where are the vectors ?
