A mass m hanging on a spring has a natural frequency f. If the mass is increased to 4m, what is the new natural frequency?

2 f.

0.25f.

4 f.

0.5 f.

A mass is attached to a vertical spring and bobs up and down between points A and B. Where is the mass located when its potential energy is a maximum?

One-fourth of the way between A and B

Midway between A and B

At either A or B

None is correct.

A mass is attached to a spring of spring constant 60 N/m along a horizontal, frictionless surface. The spring is initially stretched by a force of 5.0 N on the mass and let go. It takes the mass 0.50 s to go back to its equilibrium position when it is oscillating. What is the amplitude?

0.030 m.

0.30 m.

0.083 m.

0.83 m.
