8. A simple accelerometer can be made by suspending a small object from a string attached to a fixed point in an accelerating object - to the ceiling of a passenger car, for example. When there is an acceleration, the object will deflect, and the string will make some angle with the vertical. Find the acceleration of the object in terms of the angle the string makes to the vertical.

A 1.0 kg object is attached to one end of a 1.25 m long string. The other end of the string is fixed. The object is released from rest when the string is horizontal falls to a vertical 90-degree angle. What is the speed of the object as the lowest point along the path (when the string is vertical)? What is the value of the tension in the string at the lowest point? What is the work done by the...

A bob of mass 0.320 kg is attached to one end of a light inextensible string of length 0.600 m, whose other end is attached to a fixed pivot. The bob performs uniform circular motion in a horizontal plane, with the string making an angle of 30.0° with the vertical. What is the angular speed of this circular motion? Give your answer in raduans. (Hint: you can begin by using Newton's second law in the vertical direction to find the...
