Question

Sreshta is in her Lamborghini and trying to make a turn off a highway at 19.0 m/s. The turning radius of the curve is 35.0 m. Her car has a mass of 1240 kg.

Determine the minimum coefficient of friction required to keep the car on the road.

Answer 1

The centripetal force to make the car turn around is : .

The centripetal force is provided by the friction and the maximum friction is .

So we have , and then

. Apply the values above and you will get the minimum coefficient of friction required.
