Answer:
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.
