You're trying to pull a box has a mass of 18.67 kg up a frictionless incline that is 20 degrees above the horizontal onto a U-Haul truck. Due to the height of the box, you use a rope and your actual applied force is applied at an angle of 30 degrees relative to the ramp. What is the minimum amount of force you need to pull to prevent the box slipping down the ramp?
