A circular road of radius 50 m has the angle of banking equal to 30°. At what speed should a vehicle go on this road so that the friction is not used?

Options:

Answer:

Solution:

With no friction used, $tan θ = \frac{v ^{2}}{R g}$ :
$v = R g tan θ = 50 \times 10 \times tan 3 0^{\circ} = 288.7 \approx 17 m / s .$
