A circular road of radius 1000 m has banking angle

{45^0}

. The maximum safe speed of a car having mass 2000 kg will be, if the coefficient of friction between tyre and road is 0.5

View answer and explanation

Correct option: A

172 m/s

Option A (172 m/s) is correct because the maximum safe speed on a banked road is calculated using the formula

v = \sqrt{rg(\tan\theta + \mu)/(1 - \mu\tan\theta)}

.

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
