Arace car goes around a level, circular track with a diameter of 1.00 km at a constant speed of 89 km/h. what is the car's centripetal acceleration in m/s^2?

The car's centripetal acceleration is 1.22 m/s².

Explanation:

Given that,

Diameter of circular track

Radius r = 500 m

Constant speed

The centripetal acceleration is defined as,

Where, v = tangential velocity

r = radius

Put the value into the formula

Hence, The car's centripetal acceleration is 1.22 m/s².
