I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.
Janelle stands on a balcony, two stories above Michael. She throws one ball straight up and one ball straight down, but both with the same initial speed. Eventually each ball passes Michael. Which ball, if either, is moving faster when it passes Michael? Explain.
For an object in motion, is it possible
for velocity to be constant while
acceleration is zero? Explain.
