A 3.0 kg mass hangs from the ceiling of a railroad car. When the car accelerates to the right, the rope makes an angle of 4.0o with the vertical to the left of vertical. Find the acceleration of the car. Copied and pasted from the assignment. I swear the teacher worded it incorrectly because I cannot figure it out for the life of me
assuming lots of things, you're trying to find out what acceleration the car is in order to make the 3 kg mas hang at a 4 degree angle: where a 0 degree angle would be just a rock hanging without any movement, a 4 degree angle would be a rock that looks like its leaning slightly back--imagine when you accelerate in a car, the shit hanging from the center mirror goes back..eventually it swings the other way and just hangs there..that's because you're no longer accelerating.
