The 3000 lb car is traveling with a speed of 75 ft/s which is increaasing at a rate of 6 ft/s^2. Determine the magnitude of the resultant frictional force the road exerts on the tires of the car. Neglect the size of the car.

Rho = 600 ft

Explanation / Answer

we know that in this cas friction force is equal to centripital force

we know that to prevent slip coefficient of friction =.141

therefore friction force = u*mv^/r=3965.625
