A simple pendulum is set into motion at two different times with different initial
conditions. The first time: the bob is in its equilibrium position and is given an
initial velocity +4 m/s. The maximum height reached by the bob is h1,max and the
period of motion is T1. The second time: the bob is in its equilibrium position and
is given an initial velocity +2 m/s. The maximum height reached by the bob is
h2,max and the period of motion is T2. Assume that the motion is simple
harmonic, which of the following is true?
hz.max = 4h, a«x and T, = 27,
hzmax = h,mas/4 and T, = T,
O Then we have
O Then we nave
9h max and T = T,
h2max = 4h, and T, = 7
