1. The problem statement, all variables and given/known data A pendulum with a length of 1.00 m is realeased from an angle 15.0 degrees. after 1000s its amplitude is reduced by friction to 5.50 degrees. what is the value of b/2m. 2. Relevant equations x = Ae^-bt/2m cos(wt + phaseangle) w = root(g/L) 3. The attempt at a solution I tried setting x = 15.0 and A = 5.50 (and the reverse) and filling in t with 1000 in the exponent and in cos. (the answer in the book is 1 * 10^-3) after getting a w= 3.132 and a phase angle of 0.
