Asimple accelerometer is constructed inside a car by suspending an object of mass m from a string of length l that is tied to the car’s ceiling. as the car accelerates the string–object system makes a constant angle of u with the vertical.
(a) assuming that the string mass is negligible compared with m, derive an expression for the car’s acceleration in terms of u and show that it is independent of the mass m and the length l.
(b) determine the acceleration of the car when u 5 23.0°.
