Four springs have been compressed from their equilibrium position at x = 0 cm. When released, they will start to oscillate. Rank in order, from highest to lowest, the maximum speeds of the oscillators.

1. c > b > a = d

2. c > b > a > d

3. d > a > b > c

4. a = d > b > c

5. b > c > a = d

This is the position graph of a mass on a spring. What can you say about the velocity and the force at the instant indicated by the dotted line?

1. Velocity is positive; force is to the right.

2. Velocity is negative; force is to the left.

3. Velocity is negative; force is to the right.

4. Velocity is zero; force is to the right.

5. Velocity is zero; force is to the left.

One person swings on a swing and finds that the period is 3.0 s. Then a second person of equal mass joins him. With two people swinging, the period is

1. 1.5 s.

2. <3.0 s but not necessarily 1.5 s.

3. 3.0 s.

4. >3.0 s but not necessarily 6.0 s.

5. 6.0 s.
