The point rotates in a circle with a radius of 10m at a speed of 4m / s. What is the centripetal acceleration of this point?

The centripetal (normal) acceleration of the body is calculated by the formula:
an = V² / R, where an is the centripetal acceleration of the body (m / s²), V is the speed of the body in a circle (V = 4 m / s), r is the radius of the circle along which the body rotates (R = 10 m).
Let’s calculate the centripetal acceleration of the body:
an = V² / R = 4² / 10 = 16/10 = 1.6 m / s².
Answer: The centripetal acceleration of the body is 1.6 m / s².
