During basketball tryouts, Umass walk-on hopeful Dwayne Madison stole a pass at his own free throw line. He then spring straight down the court to the opponent's free throw line, 56ft away (1ft=0.3048m), and proceeded to throw up a brick that went over the backboard and out of the gym. If it took him 4.8 seconds to run from his free throw line to the opponent's free throw line:
What was his avg velocity (in m/s)?
If his instantaneous velocity at the midway point was 5.4m/s, and it took him 2/3 of the total time to get there:
What was his avg acceleration to the midway point (in m/s2)?
