Question

27 Find the maximum speed at which cer turns around a curve of 30 m radius on a level roa
the coefficient of friction between the tyres and the road is 0.
​

Answer 1

Answer:11m/s .

Find the maximum speed at which a car can turn round a curve of 30m radius on a level road if coefficient of friction between the tyres and road is 0.4. Takeg=10m/s2. υ=√μrg=√0.4×30×10=√120=11m/s .
