The question essentially is based on a situation like this-
A car has a small object hung from the cieling on a string (apparently at an angle of 0 degrees to the ceiling).
The car is accelerating and the object is now hanging at a 30 degree angle (to the ceiling). How would I figure out how much the car is accelerating.
PS - This is homework but Im stuck and would appreciate any advice. Thanks.
Edit: changed angle from 45 to 30.
