Final answer:

The cyclist's centripetal acceleration while turning a corner with a radius of 50 meters at a speed of 10 meters per second is calculated to be 2 m/s² using the formula a = v^2/r.

Step-by-step explanation:

Centripetal Acceleration of a Cyclist

A cyclist turning a corner with a radius of 50m at a speed of 10m/s experiences centripetal acceleration because their direction is constantly changing while moving along a circular path. To calculate the centripetal acceleration (a), use the formula:

a = v^2 / r

where v is the speed of the cyclist, and r is the radius of the circular path.

Substitute the given values into the formula:

a = (10 m/s)^2 / 50 m
= 100 m^2/s^2 / 50 m
= 2 m/s²

The cyclist's acceleration is 2 m/s², so the correct answer is C) 2m/s².
