Answer :
The centripetal acceleration of the car on the circular track is found to be 10m/s².
The car is running on a circular track at a speed of 30m/s. The radius of the circular curve is 90 m.
The centripetal acceleration of the car is given by the relation,
a = v²/r
Where is the centripetal acceleration we is the speed of the car and R is the circular radius of the curve,
Putting values,
a = (30)²/90
a = 10m/s²
So, the centripetal acceleration of the car is 10m/s².
