Nerd-A-Pult - Measuring Initial Velocity

The video tutorial explains how to measure and calculate the initial velocity of a ball launched from a device called the Nerdipult. It covers measuring the launch arm, setting up a right triangle, calculating angles using trigonometry, and determining the initial speed through frame-by-frame analysis. The tutorial concludes with a correction on significant figures.

What method was used to measure the distance the ball traveled during the first frame?

How is the average speed calculated in the context of the ball's launch?

What was the final determined magnitude of the initial velocity of the ball?
