Answer 2

Given:

Radius of road= 20m

Velocity of car= 10m/s

To find:

Banking angle (α) for a safe turn

Solution:

Curved roads are often banked to prevent the skidding of vehicles.

In this, the outer edges of the road are curved inwards to provide the required centripetal acceleration for a safe turn.

The angle at which the outer edges are raised is called the banking angle (α).

Applying the formula,

$tan\alpha = \frac{v^{2} }{rg}$

taking g = 9.8m/s²

tanα= 100/ 196

or α= tan⁻¹ 0.51

Hence the banking angle is tan⁻¹ 0.51.
