Question

A car goes around a curve with a radius of 65 meters while traveling at 22 m/s. Calculate the car's centripetal

Answer 1

Answer:

7.4 m/$s^{2}$.

Step-by-step explanation:

When an object rotates around a fixed center in a circular path  of radius R then centripetal force acts on the object ,

Centripetal acceleration equals

$\frac{v^{2} }{r}$ Where,

v is the velocity of the object rotating in circular motion

and r is the radius of the circle.

Here , r = 65 meters.

          v = 22 m/s.

Thus centripetal acceleration equals $\frac{22^{2} }{65}$

                                                              = 7.44 m/$s^{2}$.

Thus option A is the best option i.e., 7.4 m/$s^{2}$.
