The skater moves at a speed of 10m / s along a circle with a radius of 20m. Find its centripetal acceleration.

v = 10 meters per second – athlete’s speed;

R = 20 meters – the radius of the circle along which the skater moves.

It is required to determine a (centripetal) – centripetal acceleration.

To determine centripetal acceleration, you need to use the following formula:

a (centripetal) = v ^ 2 / R = 10 ^ 2/20 = 100/20 = 5 meters per second squared.

Answer: centripetal acceleration is 5 meters per second squared.
