A 50.0-kg box is being pulled along a horizontal surface by means of a rope that exerts a force of 250 N at an angle of 32.0 above the horizontal. The coefficient of kinetic friction between the box and the surface is 0.350.

What is the acceleration of the box? A) 0.638 m/s2
B) 1.74 m/s2
C) 3.16 m/s2
D) 6.31 m/s2
E) 8.53 m/s2
