of a string.A grandfather clock is "losing" time because its pendulum moves too slowly. Assume that the pendulum is a massive bob at the end of a string.The motion of this pendulum can be sped up by:- shortening the string.- lengthening the string.- increasing the mass of the bob.- decreasing the mass of the bob.
where f is the given frequency in this case 392, V is the speed of sound in air which is given as 343 and is the speed of car which is unknown, \bar f is given as 440 Hz
