A park has a radis of 10 m. If a vehicle goes round it at an averge speed of 18 km/hr, what shoud be the proper angle of banking?

Text Solution

Verified by Experts

The correct Answer is:
A, D
Radius of park r=10
S-eed of vehicle = 18 km/hr=5m/sec
Angle of banking is given by,
`tantheta=v^2/(rg)`
`rarr theta=tan^-1 25/(rg)`
`=tan^-1 25/100 =tan^-1 (1/4)`
