Question

A 75 kg Olympic sprinter runs around a track with a radius of 36.8 m with an acceleration of 7 m/s².

A. 1495.6 N
B. 2147.5 N
C. 2989.4 N
D. 3591.0 N

Answer 1

The force exerted by the Olympic sprinter while running around the track is 525 N.

Step-by-step explanation:

To find the force exerted by the Olympic sprinter while running around the track, we can use the formula for centripetal force, F = m * a, where F is the force, m is the mass, and a is the acceleration. In this case, the mass of the sprinter is 75 kg and the acceleration is 7 m/s².

So, F = 75 kg * 7 m/s² = 525 N.

Therefore, the force exerted by the Olympic sprinter is 525 N (Option C).
