A football quarterback runs 15.0m straight down the playing field in 2.50s (with a constant speed). He is then hit and pushed 3.00m straight backward in 1.75s with a constant speed. He breaks the tackle and runs straight forward another 21.0m in 5.20s (still with a constant speed). (a) Draw motion diagram of the quarterback on coordinates, define symbols at your points of interest, list known and unknown. (b) Calculate the average velocity of the quarterback for each of the three intervals. (c) Calculate the average velocity of the quarterback for the entire motion.
