Mr John is driving his car along the road. The radius of his car tyres are 0.28 m. suddenly 60 m in front of his car his angry wife stand still trying to stop him. He decelerates at 7.0 m per second to avoid hitting his dear wife. The wheel angular velocity before the deceleration was 100 rads per second. Calculate the angular acceleration of the tyre of john's car assuming they do not slip on the pavement.
