The cars on an amusement-park ride travel at a constant velocity of 4.0 m/s on a circular track
that has a radius of 4.0 m. What is the
magnitude of each car's centripetal
acceleration?
A 1.0 m/s2
B 2.0 m/s2
C 4.0 m/s2
D 16 m/s2

C) 4.0 m/s²

Explanation:

Centripetal acceleration can be found by the formula

We are given the velocity of the car, 4.0 m/s.

We are also given the radius of the circular track, 4.0 m.

Substitute these values into the formula.

The magnitude of each car's centripetal acceleration is C) 4.0 m/s².
