Question

Find the safe maximum velocity for a car moved on an unbanked circular track of radius 100m. The coefficient of friction between the road and tyre is 0.2​

Answer 1

For a car moving in a circular track, the necessary centripetal force is provided by the friction.

Let the mass of car = m

maximum velocity for over turn = v

radius of track = 100m

coefficient of friction = 0.2

Putting the values in

$\frac{m {v}^{2} }{r} = umg$

v = 14m/s

Hope it helps

Answer 2

Answer:

14 m/s is answer of your question
