Problem 14PE

A football quarterback runs 15.0 m straight down the playing field in 2.50 s. He is then hit and pushed 3.00 m straight backward in 1.75 s. He breaks the tackle and runs straight forward another 21.0 m in 5.20 s. Calculate his average velocity (a) for each of the three intervals and (b) for the entire motion.

Step 1 of 5

Average velocity of an object is defined as the displacement per unit time.We have to calculate his average velocity in each time interval and for the whole duration.
