Given information
We are given that:-
Initial velocity,
.
Final velocity,
.
Time,
.
Step-by-step explanation
Step 1.
We assume that the sprinter accelerates uniformly so that acceleration measured in meters per second square, can be obtained from this kinematic expression as a function of initial velocity and final velocity, measured in meter per second, and time , measured in seconds, as well.
We know that, , , and , the acceleration experimented by the sprinter is:
