How to find the average velocity of a ball falling

The video tutorial explains how to calculate the average velocity of a falling object. It starts by setting up the problem with initial conditions, then demonstrates the calculation of average velocity using the change in height over time. The tutorial also discusses how velocity changes as the object falls, emphasizing that the average velocity is not constant throughout the fall.

What were the initial conditions set for time and height in the problem?

• T = 0, H = 5

• T = 5, H = 0

• T = 0, H = 400

• T = 400, H = 0

How is average velocity defined in the context of this problem?

• As the instantaneous speed at a given point

• As the total distance divided by total time

• As the change in height over the change in time

• As the final velocity minus initial velocity

What was the calculated average velocity in the example?

• 180 feet per second

• -180 feet per second

• 80 feet per second

• -80 feet per second

Does the average velocity remain constant throughout the fall?

• Yes, it remains constant

• No, it varies as the object falls

• No, it only changes at the end

• Yes, but only at the start

What happens to the speed of the object as it continues to fall?

• It stops

• It decreases

• It remains constant

• It increases
