Question: In the 16th century, Galileo conducted a series of famous experiments concerning gravity and projectiles. In one experiment, he released a ball to roll down a ramp. He then measured the total horizontal distance which the ball traveled until it came to a stop. The data from that experiment occupy the first two columns of the data file. In a second experiment, a horizontal shelf was added to the base of the ramp, so that the ball rolled directly onto the shelf from the ramp. Galileo recorded the vertical height and horizontal travel for this apparatus as well, which are in the third and fourth column of the file.
