Question

A car is traveling in bank curved road of radius 125m if the coefficient of friction between the tires and road is 0.5 and g=10m/s square the maximum speed to avoid skidding is

Answer 1

by applying formula for max speed on a curved road

i.e,

v = √μRg

   =√[0.5 × 125 × 10]

    =√625

     = 25m/s

Answer 2

Given that,

Radius of the bank curved road, r = 125 m

The coefficient of friction between the tires and road is 0.5.

To find,

The maximum speed to avoid skidding.

Solution,

The maximum speed of the car to avoid skidding is given by :

$v=\sqrt{\mu gr} \\\\v=\sqrt{0.5\times 10\times 125} \\\\v=25\ m/s$

So, the maximum speed of the car to avoid skidding is 25 m/s.
