Question

if a vehicle can have maximum velocity of 72 km/hr on a smooth turn of radius 100 m what wil be the banking angle​

Answer 1

Answer: 22.2

first, let's convert km/hr to m/s

  therefore we get 20ms^-1

v= 20ms^-1

r =100m

g = 9.8

$tan\theta = \frac{v^2}{rg} \\ \theta = tan ^-1 \\\\ = \frac{20^2}{100*9.8} \\ \\ = tan^{-1} \frac{40}{98} = 0.4081$

0.4081 = 22.2
