Unformatted text preview: after t seconds. 1. a = 10 cm T = 3 seconds An object attached to a coiled spring is pushed upward a distance a from its rest position then released. Write an equation that represents the displacement of the object from its rest position after t seconds. 2. a = 6 m 5 = f Hz 3. A tuba player plays the note E and sustains the sound for some time. Find the simple harmonic equation that represents the sound wave given that the amplitude is 0.2 and the period is 1/40 second. C. Analyzing the Motion of an Object Given that the displacement, d , in meters of an object at time t (in seconds) satisfies the given equation, A) What is the maximum displacement from its resting position? B) What is the time required for one oscillation? C) What is the frequency? 1. t d 3 sin 2 = 2. t d 2 1 cos 3 =...
