A simple 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 simple 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°.
Answer:Part a)so here the angle made by the string is independent of the massPart b)Explanation:Part a)Let the string makes some angle with the vertical so we have force equation given asso we will haveso here the angle made by the string is independent of the massPart b)Now from above equation if we know that angle made by the string isso we will have...
