A box is pushed up a frictionless ramp. The box has a mass of 5.6 kg and the pushing force acts in a direction parallel to the ramp.
The ramp is at an angle of 15 degrees with the horizontal. If the acceleration of the box is 2 m/s2 up the ramp, what is magnitude of the pushing force? (Answer in Newtons)
