The body moves in a circle at a speed of 100 m / s. what is the radius, if the centripetal acceleration is 2m / s.

To calculate the radius of the circle along which a given body moves, we apply the formula: ac = V^2 / R, whence we express: R = V ^ 2 / ac.
Values of variables: V – linear speed of movement (V = 100 m / s); ac – centripetal acceleration of the body (ac = 2 m / s2).
Calculation: R = V ^ 2 / ac = 100 ^ 2/2 = 5000 m.
Answer: The radius of the circle is 5000 m or 5 km.
