Question
![A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 40 km/h at the 53-m mark.
He then maintains this speed for the next 79 meters before uniformly slowing to a final speed of 33 km/h at the finish line. Determine
the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value
occur?
Finish line
39.9 m
Correct
Calculate (a) the magnitude of the tangential acceleration near start of the race and (b) the magnitude of the tangential
acceleration near the end of the race.
Answers:
