문제 14
Ramps are useful machines when loading trucks. In one instance, a worker pulls on a trolley being loaded on a truck with an upward force F that has a direction of 28.0° with the ramp. If the ramp has a slope angle of 15.0°, what is the value of the component Fy perpendicular to the ramp when the Fx component parallel to the ramp is equal to 86.0 N?
