<h2>The velocity of car was m m/s </h2>
Explanation:
When the car skids , its centripetal force is provided by frictional force .
Here centripetal force F =
here v is the velocity of car and r is the radius of the curve .
The frictional force f = μ R
here μ is the coefficient of kinetic friction and R is normal reaction
Thus f = m g
On horizontal road R = mg
Thus F = f at the time of skid .
Thus v =
= = 9 m/s
