Question

A car is moving on a circular
level road of curvature 300m. If the coefficient of friction is 0.3 and accleratrion due to gravity is 10ms.
The maximum speed of the

Answer 1

Answer:

The answer is 30m/s^2

Or 108 kmph

Explanation:

Answer 2

Answer is

108km/h

Explanation:

Let  

Maximum frictional force  

fm  = μmg = 0.3m(10)

fm  = 3m N

For maximum speed,    (mv  )2 /r = fm

 

(mv)2/ 300 = 3 m

 v = 30 m/s

v = 30 x 18/5 = 108km/h
