A track athlete runs exactly one complete lap of the track, 400 m circumfrence, in 4.02x10^1 seconds. What is the velocity of the athlete , to two significant figures, if they are assumed to run with a constant velocity for the entire time?
Can you divide the circumference by the lap time?
That will be the average speed.
0 m/s
To determine the velocity of the athlete, we can use the equation:
Velocity = Distance / Time
Given that the distance covered is one complete lap of the track, which has a circumference of 400 m, we can substitute these values into the equation.
Velocity = 400 m / 40.2 s
Now, let's calculate the velocity:
Velocity ≈ 9.95 m/s.
Therefore, the velocity of the athlete, assuming they ran with a constant velocity for the entire time, is approximately 9.95 m/s.
