A 200 Kg Box Slides Up a 12

A 20.0 kg box slides up a 12.0 m long incline at an angle of 30.0 degrees with the horizontal. A force of 150 N is applied to the box to pull it up the incline. The applied force makes an angle of 0.00 degrees to the incline. If the incline has a coefficient of kinetic friction of 0.100, then the increase in the kinetic energy of the box is

A) 330 J.
B) 390 J.
C) 420 J.
D) 481 J.
E) 597 J.
