Find the maximum velocity for the overturn of a car moving on a circular track of radius 100 m. The co-efficient of friction between the road and tyre is 0.2
|
|
0.14 m/s
|
|
|
1.4 km/s
|
|
|
14 m/s
|
|
|
140 m/s

Explanation:
Detailed explanation-1: -Solution(By Examveda Team) 14 m/s.
Detailed explanation-2: -The maximum velocity for overturning is 14 m/s.
Detailed explanation-3: -The maximum speed of car which can be safely driven along a curve of radius 100 m is 14 m/s. So, the maximum speed of car is 14 m/s.
Detailed explanation-4: -Hint: Overturning occurs on roads when the car tries to change directions by making sharp turns. It often occurs in the case of vehicles whose center of gravity is higher from the surface of roads. Consider a car moving in a straight line and it suddenly takes a sharp turn towards the right.
