Question

A road is banked at an angle of 30° to the horizontal for negotiating a curve of radius 10√3 m. At what velocity will a car experience no friction while negotiating the curve?

Answer 1

⭐《ANSWER》

$\huge\mathfrak{\underline {\underline\pink {ANSWER}}}$

↪Actually welcome to the concept of BANKING OF THE ROAD

↪since we know that , the max velocity on a banked road with no friction is given as

〽Vmax = underoot R*g* tan@

↪since here above ,

↪R = radius of curvature , g = acceleration due to gravity , @ = inclination

↪so we get as

↪Vmax = underoot ( 10 root 3) * (10) * (1/ root 3 )

↪Vmax = underoot ( 100)

↪Vmax = 10 m/s

↪thus The safe max velocity is 10 m/s
