A mass M oscillates on a spring with a spring constant of k. If the spring is cut in half and the mass doubled, what happens to the period of oscillation? It gets smaller. None of these It gets bigger. It stays the same.

The displacement of an oscillating mass is given by x(t) = 20 cos( 5 t ). At time t = 1.5TT S, what is the velocity of the mass in m/s? A. 500 m/s B. -100 m/s C. 0 m/s D. 100 m/s E. 500 m/s

A mass suspended from a spring is raised a distance of 5 cm above its resting position. The mass is released at time t=0 and allowed to oscillate. After one third of a ​second, it is observed that the mass returns to its highest position, which was 4.5 cm above its resting position. What is the rate of change of the position of the mass at t = 2.1 seconds? Round your answer to three decimal places.

The graph shown in the figure (Figure 1) closely approximates the displacement at of a tuning fork as a function of time t as it is playing a single note.
