3. A 500-gram red ball on an air track is attached to a compressed spring (at x = 0 m the spring is unstretched) as shown in the animation (position is given in meters and time is given in seconds). Determine the spring constant of the spring (assume v = 0 m/s at the beginning and end of the animation). Restart.

4.The animation shows the analogy between circular motion (coin on a turntable) and simple harmonic motion (hanging mass on a spring). Restart. Given the animation (position is given in meters and time is given in seconds), which graph properly denotes position vs. time for a horizontal spring synchronized with the turntable?

5. The animation shows the analogy between circular motion (coin on turntable) and simple harmonic motion (hanging mass on a spring). Given the above animation (position is given in meters and time is given in seconds), what is the maximum speed of the hanging mass? Restart.
