Question

An automobile rounds a curve of radius 50.0m on a flat road at a speed of 16m/s. What centripetal acceleration is necessary to keep the car on the curve?

Answer 1

Centripetal acceleration, necessary to keep the car on the curve is $a = \frac{v^2}{R}$, where $v$ is the speed, and $R$ is the radius of the curve. Hence, $a = \frac{16^2 \frac{m^2}{s^2}}{50 m} = 5.12 \frac{m}{s^2}$.
