The situation is there is a ball attached to a string in a car, and the angle that the string makes is measured when the car is accelerating. I'm having a bit of trouble with the proof that a=tan(theta)
so far I've gotten that
weight=mg=Tcos(theta)
a=ma=Tsin(theta)
But what I don't understand is why you need to find the ratio between them and how that shows acceleration.
a/g=sin(theta)/cos(theta)
a=gtan(theta)
another one of my questions is what happens to the g in the equation?
Help is much appreciated thanks!
