Answer:
3.75 m/s^2
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by the equation:
[tex]a=\frac{v^2}{r}[/tex]
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
[tex]a=\frac{(15 m/s)^2}{60 m}=3.75 m/s^2[/tex]
