Question

What is the maximum speed at which a car could safely negotiate a curve on a highway, if the radious of the curve is 250 m and the coefficient of friction is 0.4? Give the answer in meter/sec.

Answer 1

31.3 m/s

Step-by-step explanation:

The relation between the coefficient of friction and the velocity, radius of curve path is given by

μ = v^2 / r g

v^2 = μ r g

v^2 = 0.4 x 250 x 9.8 = 980

v = 31.3 m/s
