The student in item 1 moves the box up a ramp inclined at 12° with the horizontal. if the box starts from rest at the bottom of the ramp and is pulled at an angle of 25.0° with respect to the incline and with the same 185 n force, what is the acceleration up the ramp? assume the coefficient of kinetic friction is 0.27.
