1. Person is climbing a mountain with rope attached to rock on a flat surface above for support. The slope has an incline angle of 50 degrees. The rock is on frictionless ground, and the mass of the rope can be ignored. The person (100 kg) is 3 meters from the flat surface, the rock (700 kg) is 6 meters from the edge. What is the minimum acceleration the person needs to climb up at to reach the edge before the rock does. All surfaces are frictionless.
2. I do not know what equations to use :(
3. I attempted by finding the downward acceleration of the person, when he is not moving, and finding that his upward acceleration must be double that.
