With what centripetal acceleration does a car move along a convex bridge with a radius of 75 m, if its speed is 54 km / h?

Problem data: R (radius of the convex bridge along which the car is moving) = 75 m; V (constant speed of the vehicle in question) = 54 km / h.

SI: V = 54 km / h = 15 m / s.

To calculate the centripetal acceleration of the vehicle under consideration, it is necessary to divide the square of its speed by the value of the axle radius: an = V ^ 2 / R.

Let’s make a calculation: аn = 15 ^ 2/75 = 225/75 = 3 m / s2.

Answer: The car in question will move with a centripetal acceleration of 3 m / s2.
