An object rests on a ramp that is angled at 20 above the horizontal. What direction (relative to the vertical) will the normal force from the ramp point?
Answer
The normal force will be directed exactly upward, along the vertical.
The normal force will be directed 20 to the right of vertical.
The normal force will be directed 70 to the right of vertical.
The normal force will be directed horizontally, 90 to the right of vertical.
