A) Using information you gathered in Chart 3 as well as the three linear motion equations (in the appropriate form, i.e. using "x" or "y"), calculate how long it takes for the ball to reach its peak. In the photo the ball reaches its peak right between the 6th and the 7" image. (You know this because those two images are at the same height.) Compare (using a percent error) your calculated value to this time value that is right between 6" and the 7" image. (Yes, you have to calculate this time value.)
