Physics 120 - Heat, Waves, and Light Resources Log In Log Out Set 8 Problem 4 A mass 23.1 (in grams) suspended from a string of length 99 (in cm) forms a simple pendulum. If its amplitude is 0 (in degrees), during what fraction of its period can the pendulum be found between + 0 . and - 0 ? The initial amplitude is small enough that the motion is simple harmonic to a very good approximation. Express your answer in terms of the given variables. fraction = ab sin(x) Ox10 Submit Reset Reset All Use O(t) = 00 sin(w t) to find wt, given 0(t) and 00- Note that w can be expressed in terms of the period of the motion. How many times in one cycle does the pendulum swing through the range between 0 . and - 0 .? Evaluate numerically using the values m = 23.1 g, L = 99 cm, 0 = 5.3 . and 00 = 9.7 . 15 O. fraction = ab sin(X) 0x10 Submit Reset Reset All Check that your calculator is in radian mode
