1. The problem statement, all variables and given/known data A 30 kg box is on a frictionless floor. The box is being pulled with a force of 120 N at an angle of 15 degrees. Find the normal force. Why is the normal force not equal to simply the gravitational force. What would make the person pull the box vertically into the air? 2. Relevant equations Fg = mg 3. The attempt at a solution I solved for the horizontal component of the applied force, added it to the normal force, and set it equal to 0 plus the gravitational force (30 * 9.8 = 294 N). I think I have done the first part correctly, but I am not sure how to answer the second two parts.
