15. How is the formula for Simple Harmonic Motion modified for when the motion is damped? What does increasing the damping coefficient do to the graph of the motion? B i U Font Family 16. What function describes the position (as a function of time) of an object in Simple Harmonic Motion, and why is an appropriate function to model the behavior? B i U Font Family -AA- A OF . 18 . E . 90 018. A object on a spring is oscillating according to the equation of motion for damped oscillator: y = Ag at sin (w . t) If the damping coefficient is 0.20, the angular frequency is 2.0 s", what is the amplitude if the position of the object at time t = 1.0 sec is 1.6 m? 10.5 m 7.6m 2.9m 2.1 m 19. What is the relationship between a spring constant, the force applied to an object attached to the spring, and the amount the spring will stretch? B / U Font Family - A- A / 5 - 19 . E . 9 9020.
