Question5. (I) What is the maximum speed with which a 1200kg1200-\mathrm{kg} car can round a turn of radius 90.0 m on a flat road if the coefficient of static friction between tires and road is 0.65 ? Is this result independent of the mass of the car?

Studdy Solution
Discuss the independence of the result from the mass of the car: The mass m m cancels out in the equation μsmg=mv2r \mu_s mg = \frac{mv^2}{r} , showing that the maximum speed is independent of the mass of the car.
The maximum speed with which the car can round the turn is approximately:
23.94m/s \boxed{23.94 \, \text{m/s}}
