A cyclist riding the bicycle at a speed of 14 3 m s - 1 takes a turn around a circular road of radius 20 3 m without skidding. Given g = 9.8 m s - 2 What is his inclination to the vertical ?

Options

  1. A30 °
  2. B90 °
  3. C45 o
  4. D60 °

Correct answer

D. 60 °

Step-by-step solution

θ = t a n - 1 v 2 r g = t a n - 1 ( 14 3 ) 2 20 3 × 9.8 = t a n - 1 [ 3 ] = 60 °
