5. A car is moving with a speed of 30 m/s on a circulartrack of radius 500 m. Its speed is increasing at arate of 2.0 m/s2. Determine the magnitude of itsAns. 2.7 m s 2.9.acceleration |

Answer» The centripetal acceleration is = v²/r = 30*30/500 = 9/5 m/s² = 1.8 m/s² and the tangential acceleration is = 2m/s² so net acceleration = √(2)²+(1.8)² =√7.24 = 2.7 m/s² thanks |
