QUESTION 25 A worker moves a 20-kg crate on a level surface by pulling on the free end of a light, uniform cable whose other end is attached to the crate. The resultant tension in the cable is 200 N at an angle of 300 above the horizontal. (See the diagram below.) If the coefficient of friction between the crate and the surface is uk = 0.40, what is the resultant acceleration of the system? Fext a. 3.9 m/s2 b. 3.2 m/s2 C. 6.7 m/s2 С. d. 1.8 m/s? e. 4.6 m/s2
