The train moves along a curve with a radius of 500 m at a speed of 36 km / h. What is its centripetal acceleration equal to?

To determine the centripetal acceleration of the train in question, we use the formula: an = V ^ 2 / R, where V is the constant speed of the train in question (V = 36 km / h, in SI V = 10 m / s); R – radius of curvature (R = 500 m).

Let’s perform the calculation: an = 10 ^ 2/500 = 0.2 m / s2.

Answer: The centripetal acceleration of the train in question was 0.2 m / s2.
