1. The problem statement, all variables and given/known data A beetle takes a joy ride on a pendulum. The string supporting the mass of the pendulum is 170 cm long. A) If the beetle rides through a swing of 43 degrees, how far has he traveled along the path of the pendulum? B) What is the displacement experienced by the beetle while moving through the same angle 43 degrees? C) If the pendulum at some instant is swinging at 3.3 rad/s, how fast is the beetle traveling? 2. Relevant equations theta = s/r 3. The attempt at a solution A) 43/360 * (2pi * 170) = 127.584 cm - correct B) s = r(theta) s = 170 x 43(pi/180) = 127.584 cm - incorrect C) theta = s/r 3.3 = s/170 s = 561 cm/s - correct I don't know what I did wrong for part b. Perhaps I am supposed to multiply by pi/360?
