If a baseball falls a vertical distance of 2.6 m from the first to the last image, what is the time interval between the first and last image?

Well, since we're talking about a baseball falling, I'm guessing that the time interval is not going to be too long. After all, baseball players are known for their need for speed...on the field at least. But back to the question, we can use a handy formula to figure it out. The formula for calculating the time it takes for an object to fall is t = √(2h/g), where h is the vertical distance and g is the acceleration due to gravity. So, plugging in the numbers, we get t = √(2 × 2.6 m / 9.8 m/s^2). Crunching the numbers, we find that the time interval between the first and last image is approximately 0.64 seconds. Not bad for a baseball on a mission to touch the ground!
