An athlete completes 4 laps around a track with a radius of 25 meters in 12 minutes (720 seconds). What is the magnitude of the athlete's tangential velocity?

The athlete's tangential velocity is 0.88 m/s.

Step-by-step explanation:

We have that the athlete completes 4 laps around a track with a radius of 25 meters in 12 minutes:

Where:

ω: is the angular speed

θ: is the angular displacement

t: is the time = 12 min = 720 s

The angular displacement is:

Now, the angular speed is:

Finally, the athlete's tangential velocity is:

Therefore, the athlete's tangential velocity is 0.88 m/s.
