The skater moves at a speed of 10m / s along a circle with a radius of 20m. Find its centripetal acceleration.
February 16, 2021 | education
| 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.
