Two sprinters start a race along a straight track at the same time and cross the finish line at the same time. 1) are their average velocities necessarily equal? a. yes, their average velocities would be equal since two sprinters run the same displacement during the same amount of time. b. no, their average velocities might not be equal since two sprinters could run at different instantaneous velocities.2) are their instantaneous velocities necessarily always equal? a. yes, the two sprinters run the same displacement during the same amount of time. b. no, one sprinter might go faster during one part of the race and slower during the other part.3) are their final velocities necessarily equal? a. yes, the final velocity is the instantaneous velocity at the moment a sprinter crosses the finish line, which will be the same between the two sprinters. the instantaneous velocities for the entire race must be the same. b. no, the final velocity is just the instantaneous velocity at the moment a sprinter crosses the finish line, which can vary between the two sprinters. only the average velocity for the entire race must be the same.& explain (in simpler terms). you : )
