Question
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.
30°
angular speed =
1
What is the angular speed of this circular motion? Give your answer by entering a
number, correct to an appropriate number of significant figures, in the empty box below.
rad s-1.
m
(Hint: you can begin by using Newton's second law in the vertical direction to find the
tension in the string.)
