The mass is given a small vertical displacement, and the system is allowed to oscillate. Electronic data collection apparatus is used to measure the position of the mass, and a graph of position versus time is created. The graph indicates that the system is lightly damped. $RIncorrect Answer The provided answer is not correct and no specific feedback is available. Please view available hints and review the relevant material. Close and stay on this question $ Students count the number of oscillations that occur until the amplitude has decreased to 66.5% of its initial value. From this, it is determined that the damping coefficient is b = 2.58 x 10~ kg/s. How many oscillations did the students count?
