Question

a motor car travelling at a speed 75km per hour at a radius 60m.if the road is banked at an angle60°. will the car be safe or not?
​

Answer 1

Answer:

Given that  Maximum speed for a car on a road= 25m/sec

                   Radius of curvature = 60 m  

Let θ be the angle of banking  

⟹θ=tan  −1 rg v  2

  =tan  −1

  60×10 625

​⟹θ=tan  −1

  600 625

​

⟹θ=47
