A car moving on circular level road if radius of curvature 300m if coefficient of friction is 0.3 and accelerates due to gravity the minimum speed of car |
|
Answer» Answer: 30 m/s Explanation: When the CAR is moving on a level circular ROAD then, centripetal force is supplied by frictional force mv²/r = μmg v = √(μrg) v = √(0.3 × 300 m × 10 m/s²) = √(900 m²/s²) = 30 m/s This is the maximum speed the car can travel, ALSO called safe. |
