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
