On a highway turn, the car moves with a constant modulus of 10m / s. What is the centripetal acceleration, the radius of the highway curvature is 50m?
The centripetal acceleration a when moving in a circle is calculated by the formula:
a = v ^ 2 / R, where v is the linear velocity, R is the radius of curvature.
a = (10 ^ 2 m ^ 2 / s ^ 2) / 50 m = (100/50) m / s ^ 2 = 2 m / s ^ 2.
Answer: The centripetal acceleration of a car is 2 m / s ^ 2.
