Instead of moving back and forth, a conical pendulum moves in a circle at constant speed as its string traces out a cone (see figure below). One such pendulum is constructed with a string of length L = 14.9 cm and bob of mass 0.326 kg. The string makes an angle 𝜃 = 6.84° with the vertical.
(a) What is the radial acceleration of the bob?
[answer] magnitude m/s^2
(b) What is the horizontal and vertical components of the tension force exerted by the string on the bob? (Assume radially inward to be the positive x axis and vertically upward to be the positive y axis. Express your answer in vector form.)
