(Ch 15 HW- Part 2 Problem 15.74 A small 3.0-kg object dropped from the roof of a tall building acquires a terminal speed of 35 m/s. Assume the drag torce exerted on the object has the same form as the damping force exerted on a damped oscillator; that is, the force is opposed to the motion, and its magnitude is linearty proportional to the object sspeed. An object identical to the dropped one is attached to a vertical spring (k- 290 N/m) and set into oscillation in the air with an initial amplitude of 0.30 m. Part A What is the quality factor for this oscillation? Submit Reguest Answer Part B How long does it take for the amplitude to drop to half its initial value? Express your answer with the appropriate units. HA t1/2- Value Units Subnit Request Answer
