Lucille Eaton · Answer 1

For this case, the friction force acting on the sled will be of the same magnitude as the horizontal component of the force that is being applied at 30 degrees above the horizontal since the velocity is constant. Therefore, the result will be given by:

F = 60 * cos (30) = 51.96N

the magnitude of the frictional force acting on the sled is 51.96 N
