a swimmer speeds up from 2 m/s to 6 m/s during the last 20 seconds of the race. what is the acceleration of the swimmer?
If an object's velocity changes from 2 meters per second to 6 meters per second in five seconds, its acceleration is calculated as follows:-
6-2)/20 = 80m per second per second or or 80m per second squared (m/s2)

Scientists do their experimental tests more than once so they effects of chance errors.
