Answer: Acceleration of the runner =1.23 m/s²
The distance covered by the runner will be 99.9 m
Explanation: Given,
Velocity=11.1 m/s²
Time= 9 seconds
Acceleration=?
Acceleration = Velocity/Time
Acceleration = 11.1 / 9
Acceleration = 1.23 m/s²
The distance covered by the runner= 11.1 m/s² × 9 seconds
The distance covered by the runner= 99.9 m
