As your jet plane speeds down the runway on takeoff, you measure its acceleration by suspending your yo-yo as a simple pendulum and noting that when the bob (of mass 725 g) is at rest relative to you, the string (of length 52.8 cm) makes an angle of 33° with the vertical. the acceleration of gravity is 9.81 m/s^2. find the period for small oscillations of this pendulum.
