What is the normal acceleration of a car when it travels at a speed of 100 km / h with an arched, convex bridge with a radius of curvature of 1200 meters.
The normal (centripetal) acceleration of a vehicle can be calculated using the following formula:
an = V² / R, where V is the linear speed of the vehicle (V = 100 km / h, in m / s 100 km / h will be 27.78 m / s), R is the radius of the vehicle’s trajectory (radius of curvature of the bridge, R = 1200 m).
an = V² / R = 27.782 / 1200 ≈ 0.64 m / s2.
Answer: The car acquires a normal acceleration of 0.64 m / s2.
