A 7.5 kg box initially at rest on a horizontal surface is pushed by a constant force of 34.2 N that is applied at angle 35.6° below the horizontal. As the box accelerates along the surface, it encounters a frictional force of 16.6 N. Using work-energy theorem, what is the speed of the box after it has traveled 4.75 m? Vi = 0 of d O 7.50 m/s 5.93 m/s O 3.77 m/s O 4.72 m/s m
