Question: 2. When a pendulum 0.5 m long swings back and forth, its angular displacement 0 from rest position, in radians, is given by 0(t) =

2. When a pendulum 0.5 m long swings back and forth, its angular displacement 0 from rest position, in radians, is given by 0(t) = sin 2 t , where t is the time, in seconds. At what time(s) during the first 4 s is the pendulum displaced 1 cm vertically above its rest position? (Assume the pendulum is at its rest position at t = 0.) vVV VV
