Question #1468

What is the maximum speed with which a 1050 kg car can round a turn of the radius 70 m on a flat road if the coefficient of friction between tires and road is 0.80?

Expert's answer

The acceleration due to change in the direction is:

& a = V2/R

Let's write the equation of the force equilibrium

micro; m g = m a

micro; g =& V2/R

V 2= R µ g = 70*0.8 * 10 = 560

The maximum speed would be equal to 23.66 m/s.

& a = V2/R

Let's write the equation of the force equilibrium

micro; m g = m a

micro; g =& V2/R

V 2= R µ g = 70*0.8 * 10 = 560

The maximum speed would be equal to 23.66 m/s.
