A $20.0 \mathrm{~kg}$ Box Slides Down A $12.0 \mathrm{~m}$ Long Incline at an Angle of 3

A $20.0 \mathrm{~kg}$ box slides down a $12.0 \mathrm{~m}$ long incline at an angle of 3.0 degrees with the horizontal. A force of $50.0 \mathrm{~N}$ is applied to the box to try to prevent it from sliding down 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) $525 \mathrm{~J}$ .
B) $455 \mathrm{~J}$ .
C) $300 \mathrm{~J}$ .
D) $372 \mathrm{~J}$ .
E) $410 \mathrm{~J}$ .
