Instantaneous vs Average Velocity
1. Emilio drops a tennis ball from a height of 5 meters above the ground. It takes 1 s for the ball to hi
-5 m/s, and concludes that the
-5m
1s
=
the ground. He calculates the velocity of the ball from v =
ball had a velocity of 5 m/s after it hit the ground.
a. Is Emilio's work correct? Why or why not?
opeb. What is the actual velocity of the ball when it hit the ground?
c. What does the -5 m/s Emilio calculated represent?
