A $6.00 \mathrm{~kg}$ Box Is Pulled Up An $8.00 \mathrm{~m}$ Long Incline (With Friction) at an Angle of 30

A $6.00 \mathrm{~kg}$ box is pulled up an $8.00 \mathrm{~m}$ long incline (with friction) at an angle of 30.0 degrees by a force of $50.0 \mathrm{~N}$ parallel to the incline. The coefficient of kinetic friction is 0.100 . The work done against friction is

A) $40.7 \mathrm{~J}$ .
B) $30.3 \mathrm{~J}$ .
C) $22.0 \mathrm{~J}$ .
D) $26.5 \mathrm{~J}$ .
E) $35.2 \mathrm{~J}$
