Answer:
Maximum constant speed with which a car can round is 20.76 m/s.
Explanation:
We know, for car to be move on flat road without slipping its centripetal force should not exceed static friction.
Therefore, maximum value of friction must be equal to centripetal force.
Therefore, [tex]\dfrac{mv^2}{r}=\mu_smg[/tex]
Now, putting all given values and [tex]g = 9.8 \ m/s^2[/tex].
We get , [tex]\dfrac{v^2}{80}=0.55\times 9.8\\\\v^2=0.55 \times 9.8\times 80\\v=20.76\ m/s.[/tex]
Hence, this is the required solution.
