A curved in a level road has a radius \( 75 \mathrm{~m} \). The maximum speed of a car turning this curved road can be \( 30 \mathrm{~m} / \mathrm{s} \) without skidding. If radius of curved road is changed to \( 48 \mathrm{~m} \) and the coefficient of friction between the tyres and the road remains same, then maximum allowed speed would be \( \mathrm{m} / \mathrm{s} \).
