A park has a radius of 10 m. If a vehicle goes round it at an average speed of 18 km/hr, what should be the proper angle of banking?
Average speed, v =18km/hr
= 18 × 5/18 m/s
= 5 m/s
Radius of park, r = 10 m
Acceleration due to gravity, g = 10m/s2
We know,
The angle of banking, θ = tan-1(v2/rg)
= tan-1(52/10×10)
= tan-1(1/4)
