What is the centripetal acceleration of a body moving along a circle with a radius of 15 cm with a period of 4 s?

Initial data: R (radius of the circle along which the body moves) = 15 cm; T (orbital period of a given body) = 4 s.

SI system: R = 15 cm = 0.15 m.

The centripetal acceleration of the body can be calculated by the formula: an = 4 * Π ^ 2 * R / T ^ 2.

Let’s make the calculations: an = 4 * 3.14 ^ 2 * 0.15 / 4 ^ 2 = 0.37 m / s2.

Answer: The centripetal acceleration of the body is 0.37 m / s2.
