6. (5 points) Figure 4 shows a person pulling a 25-kg crate a distance d = 7.0 m across a floor and to the right with a rope. The tension in the rope is T-180 N and makes an angle of 37° with the horizontal. The coefficient of kinetic friction between the crate and the floor is is μ = 0.3. The work done by the force of kinetic friction on the block is Figure 4 (A) 919 J (B)-287J (C)-742] (D) -158 J (E)-174 J (F)-560 J
