A mass is suspended from a vertical spring where one end is fixed. Let O be the equilibrium position where the suspended mass rests vertically below the spring. The mass is subsequently displaced downward by a distance A from point O. A mass on a spring bounces up and down in simple harmonic motion, modeled by the function y(t) = 6sin(t) where y is in centimeters (cm) and t is measured in seconds. Find the rate at which the spring oscillates at t = 5 s. A pendulum consisting of a sphere suspended from a light string is oscillating with a small angle with respect to the vertical. The sphere is then replaced with a new sphere of the same size but greater density and is set into oscillation with the same angle. How do the period, maximum kinetic energy, and maximum acceleration of the new pendulum compare to those of the original pendulum? If the length of a simple pendulum is quadrupled, its period will: A) DoubleB) QuadrupleC) Stay the sameD) Decrease by half E) Decrease by one-fourth.
