Question

A car goes around a curve of radius 60 m at a constant speed of 15 m/s. Which of the following values is the centripetal acceleration of the car?

Answer 1

3.75 m/s^2

Step-by-step explanation:

The centripetal acceleration of an object in uniform circular motion is given by the equation:

`a=(v^2)/(r)`

where

v is the tangential speed of the object

r is the radius of the trajectory

In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is

`a=((15 m/s)^2)/(60 m)=3.75 m/s^2`
