An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds. What is the average acceleration of the sprinter?
a = change in velocity/change in time
= (11 - 0) / 10
= 1.1 m/s^2
I think that's right what he or she said is right
To find the average acceleration, we need to divide the change in velocity by the change in time.
The change in velocity is the difference between the final velocity and the initial velocity. In this case, the sprinter goes from a state of rest (initial velocity = 0 m/s) to a velocity of 11 m/s (final velocity). So the change in velocity is 11 m/s - 0 m/s = 11 m/s.
The change in time is given as 10 seconds.
To calculate the average acceleration, we divide the change in velocity by the change in time:
Average acceleration = change in velocity / change in time
= 11 m/s / 10 s
= 1.1 m/s²
So, the average acceleration of the sprinter is 1.1 m/s².
