Yes, I’m repeating images. it’s because I had a great idea for an AP problem. show them the video and have them calculate the vibrational frequency of the bat assuming hooke’s law.
Here is the step by step process I hope they follow:
• use kinematics to get the force is the bat on the ball
• use the third law to get the force on the bat.
• estimate the max displacement of the bat.
• look up the mass of the bat and get the vibrational frequency.

I think this will be a great way to spend Monday.
