Question

A circular race track of radius 300 m is banked at an angle 15 degree

Answer 1

(1)

The optimum speed of the racing car is

given as

vo = [Rgtanθ]1/2

here,

R = 300m

θ = 15o

so,

vo = 300 x 10 x tan15

thus,

vo = 28.06 m/s. ..(2)

The maximum permissible speed is given as

here,

μ = 0.2

so,

thus, we get

vm = 38.13 m/s
