Question 662: Centre of Mass and Rotational Motion

Question

A car of mass 1000 kg negotiates a banked curve of radius 90 m on a frictionless road. If the banking angle is 45o, the speed of the car is

Accepted Answer

Here, m = 1000 kg, R = 90 m, $$	heta $$ = 45ÃÂ°
For banking, $$	an 	heta  = {{{v^2}} \over {Rg}}$$
$$ \Rightarrow v = \sqrt {Rg	an 	heta }  = \sqrt {90 	imes 10 	imes 	an {{45}^o}}  = 30\,m{s^{ - 1}}$$
