do the wet of course
.35 m g = m Ac = m v^2/R
so v^2 = .35 *9.81 * R
You need to know R, the turn radius
An engineer is trying to determine the maximum speed at which a vehicle travel around the curve without skidding. She know the coefficient of friction between the wheels and the road is 0.75 when the road is dry and 0.35 when the road is wet. She knows that the mass of the vehicle does not matter, but completes her calculations for a 900kg car.
Answer questions for the case when the car is traveling at the maximum speed that will allow it to navigate the in both wet and dry conditions.
Should she perform her calculations with the coefficient of friction for wet or day pavement?
In this case, what is the car's centripetal acceleration?
m/s2
In this case, what is the car's speed?
m/s
mph
Could vehicles, obeying a speed limit of 65mph, navigate the curve on wet or dry pavement?
