Question

A sled of mass 20 kg is being pulled along a level horizontal surface my man exerting a force of 110 n at an angle of 36.9 above the horizontal. Due to friction between the sled and the ground the sled moves at constabt velocity. A) what is the force of friction acting on the sled? B) what is the normal force between the sled and the ground?

Answer 1

Given data:

* The mass of the sled is 20 kg.

* The force exerted by the man on the sled is 110 N.

* The force on the sled is at the angle of 36.9 degree above the horizontal.

Solution:

The representation of the given system is as,
