Homework
Is the horizontal component of the projectile’s velocity constant?
If you pause the video right as the ball initially hits the board and watch a few frames afterward, you can see the ball is progressing downward in a linear fashion. I can’t read the numbers not due to myopia; the numbers are actually illegible on my lap top but by taking the slope of the line the ball creates, you can determine the velocity. Right?

Another question . . . What is the acceleration of the ball? This can be determined by taking the velocity vs time and graphing, right?

I do not have acess to any digital cameras or videoplayers :[[[. Oh well. I believe in the heat death of the Universe.I'm a Kelvinist.

You know this has happened to you--especially upon being late for homeroom.
