Question
A football quarterback runs 11.5 m straight down the playing field in 2.42 s. He is then hit and pushed 2.75
m straight backward in 1.64 s. He breaks the tackle and runs straight forward another 23.1 m in 5.54 s.
We assume the forward direction to be positive, and the backward position to be negative.
Calculate his average velocity in m/s
a. for each of the three intervals;
b. for the entire motion.
Hint
a. His average velocities for each of the three intervals are
o first interval v₁ =
m/s
Enter an integer or decimal number [more..]
m/s
o second interval v₂ =
m/s
othird interval v3 =
b. His average velocity for the entire motion is v =
m/s
