1. The problem statement, all variables and given/known data A crate is stuck in quicksand. The man trying to get the crate out of the quicksand thinks that a force of 2700 N applied in the direction r2 will be sufficient to get the crate free. The crate also has a cable attached to it that is connected to a mechanical crank in the direction r1. The cable can withstand up to 4500 N of force before snapping. r1 = <400, 1200, 300> m r2 = <-4, 8, -2> m Will the man be successful in getting the crate out of the quicksand? 2. Relevant equations unit vector = position vector / magnitude of position vector 3. The attempt at a solution I found the unit vectors for r1 and r2, but I'm not sure what to do next. I can convert F1 and F2 to Cartesian components using the unit vectors and their magnitudes, but how can I determine if the crate moves without knowing its weight? Thanks for any help.
