A ball on an air track is attached to a compressed spring as shown in the animation (position is in meters measured from equilibrium and time is in seconds) Each of the four animations shows the same motion of the ball, but a different associated graph.

Explanation / Answer

1. Animation 1

2. initial position should be negative as spring is compressed and then the position should move towards positive as the spring will expand towards positive direction.

3. Animation 3

4. As initial velocity must be zero as spring is completely compressed and then velocity will be positive as the spring will move towards positive direction while expanding.

5. animation 2

6. as initial value of acceleration is maximum adn positive as acceleration is toward positive direction which goes on decreasing as spring further expands.

7. 1.6

8. as the peak is above 1.5 and below 2.

9. .16 hz

10. as frequency lesser than 1/5=.2

11. 1.6 m/s^2

12. as peak is between 1.5 and 2
