Question

A 1.5 Kg car moving on a flat , horizontal road negotiates a curve. If the radius of the curve is 35 m and the coefficient of static friction between the tires and dry pavement is 0.5, find the maximum speed the car can have and still make the turn successfully.

Answer 1

maximum speed=(cfsf×r×g)^1/2

=(0.5×35×9.8)^1/2

=(171.5)^1/2

=13.09m/s

Answer 2

HEYA GM ^_^

R = 35m , Mu = .5

Safe Velocity of turning = √mu×g×r. √.5 × 10 × 35 = √5×35 = √175 = 13.2 m/s
