Physics

To find the total distance traveled by the runner, we will calculate the distance covered during the acceleration phase and the distance covered at constant speed.

 

Phase 1: Acceleration

The runner accelerates from 3 m/s to 9 m/s in 2 seconds. We can calculate the acceleration (a) first using the formula:

 

Then, we can calculate the distance covered during this acceleration phase using the formula:
