Problem 1DQ

Which of the following formulas is valid if the angular acceleration of an object is not constant? Explain your reasoning in each case.

Step-by-Step Solution:

Solution 1DQ Step 1: Option (a) is valid because, it is obtained from the arc length formula s = r, this is valid for all the instances of time irrespective constant acceleration and not Option (b) is valid as the tangential component of the acceleration is rate of change of linear velocity Option ( c) not valid , as this is assumption made to obtain the acceleration along the uniform path Option (d) is valid as it depends on the linear speed of the particle which in turn depends on the angular velocity Option (e) is not valid as the value of I gets greater the object gets rigid
