    A curve in a level road has a radius 75 m75\text{ }m. The maximum speed of a car turning this curved road can be 30 m/s30\text{ }m/s without skidding. If radius of curved road is changed to 48 m48\text{ }m and the coefficient of friction between the tyres and the road remains same, then maximum allowed speed would be ____\_\_\_\_ m/sm/s.

    A car is moving on a horizontal curved road with radius 50 m50\text{ }m. The approximate maximum speed of car will be, if friction between tyres and road is 0.34. [take g=10 ms−2g = 10{\text{ }ms}^{- 2} ]
