The car moves at a speed of 54 km / h on a convex bridge with a radius of curvature of 30 m.

The car moves at a speed of 54 km / h on a convex bridge with a radius of curvature of 30 m. What is its centripetal acceleration equal to?

To find out the centripetal acceleration of the presented car, we will use the formula: an = V ^ 2 / R, where V is the speed of the presented car (V = 54 km / h, in the SI system V = 15 m / s); R is the radius of curvature of the bridge (R = 30 m).

Let’s make a calculation: an = V ^ 2 / R = 15 ^ 2/30 = 7.5 m / s2.

Answer: On the convex bridge, the presented car was moving with a normal acceleration of 7.5 m / s2.
