located when its kinetic energy is a maximum?

1. at either A or B

2. midway between A and B

3. one-fourth of the way between A and B

4. none of the above

Question 2

A mass of 200g hung from an ideal spring causes it to stretch by 8.40 cm.

What is the frequency (f) of oscillation for this spring/mass system?

1. 1.72 Hz 2. 3.03 Hz

3. 19.0 Hz 4. 72.3 Hz

Question 3

A pendulum has a period of 2.0 s on Earth. What is its length?

3. 0.70 m 4. 0.50 m

Question 4

The mass of a pendulum is doubled. What affect does this have on its frequency?

1. No effect

2. It causes the frequency to decrease.

3. Ir causes the frequency to increase.
