A curve in a stretch of highway has radius R. The road is not banked in any way. The coefficient of static friction between the tires and the road is . What is the fastest speed that a car can safely travel around the curve

Respuesta :

Answer:

maximum possible velocity = [tex]\sqrt{ugR}[/tex]

Explanation:

centripetal acceleration when the  car is going in the circle must be less than the maximum friction for the car to not slip.

centripetal acceleration [tex]\frac{mv^{2}}{r}[/tex]

where v is the velocity of car and r is the radius of circle

maximum friction = umg

where u is the coefficient of static friction.

therefore[tex]umg\geq \frac{mv^{2}}{R}[/tex]

therefore maximum possible velocity = [tex]\sqrt{ugR}[/tex]
