A bicyclist of mass 112 kg rides in a circle at a speed of 8.9 m/s. If the radius of the circle is 15.5 m, what is the centripetal force on the bicyclist?

The centripetal force, Fc, is calculated through the equation,

Fc = mv²/r

where m is the mass, v is the velocity, and r is the radius.

Substituting the known values,

Fc = (112 kg) (8.9 m/s) ² / (15.5 m)

= 572.36 N

Therefore, the centripetal force of the bicyclist is approximately 572.36 N.
