The car moves on a bend along an arc of a circle with a radius of 100 m with a constant modulus of speed 8 m / s. What is the acceleration of a car?

To solve this problem, you must use a well-known formula from a physics course. Calculation of the centripetal acceleration of a body moving in a circle. Where A is the centripetal acceleration of a moving vehicle. V – Vehicle speed. R – The radius of the circle along which the vehicle is moving.

F = M * A = M * V ^ 2 / R. From here we find the acceleration.

A = V ^ 2 / R = (8m / s) ^ 2/100 (m) = 64 (m2 / s2) / 100 (m) = 0.64 (m / s2).

Answer: the centripetal acceleration of a car moving in a circle is A = 0.64 (m / s2).
