A crate is dragged 4.0 m along a rough floor with a constant velocity by a worker applying a force of 400 N to a rope at an angle of 30∘ to the horizontal.
For the crate moving along the direction of Force with constant velocity the summation of the force alng x-axis should be zero. and too for the y component In view of this Fx=Fcos30 =364.4N
