Hi -

Grateful for your experts opinion on the question below to compare with my own answer please ?

A bob of mass m= 0.120 kg is attached to one end of a light inextensible string and swung in a vertical circle of radius r= 0.600 111. The string has a breaking tension (the maximum tension the string can be subjected to without breaking) of 50.0 N. Calculate the maximum angular speed of the bob at the bottom of its swing if the string is not to break at this point. You may assume that, near the bottom of the swing, the bob is effectively in uniform circular motion. Give your answer by entering a number, correct to an appropriate number of significant figures, in the empty box below. maximum angular speed = rad 51
