Question

the maximum safe speed of a car rounding an unbanked corner is 16 m s-1 when the road is dry. The maximum frictional force between the road surface and wheels of the car is halved when the road is wet. What is the maximum safe speed for the car to round the corner when the road is wet?
​

Answer 1

Explanation:

The maximum safe speed for a vehicle taking a turn on a curved banked road

is given by v2=μ∗rg

hence μ2μ1=v22v12=152:102=9:4

Answer 2

Answer:

Explanation:use centripetal force formula mvsquared upon r

Then both the centripetal force for wet and dry roads should be equal.

Hence equal both equations and find v
