A car of mass 2000 kg is moving with a speed of 10 metre per second on a circular path of radius 20 meters on a level road what must be the frictional force between the car and the road so that the car does not slip.
Answers
Explan.
The mass of the car is m=1500kg
The radius of the track is r=20m
The speed of the car is v=12.5ms−1
The frictional force is equal to the centripetal force to prevent slipping
Fr=mv2r=1500⋅12.5220=11718.75N
Answer:
Thus, the required frictional force between the car and the road so that the car does not slip is .
Explanation:
Concept:
The opposing force that is produced when two surfaces attempt to move in the same direction or in opposite directions is known as frictional force. A frictional force is primarily intended to produce resistance to the mobility of one surface across another surface.
Given:
Mass of car
Speed
Radius of the path
To find:
To prevent the car from slipping, we must determine the frictional force between the road and the vehicle.
Solution:
Frictional force will function in a manner that generates the required centripetal force, preventing sliding. I.e., the centre of the circular curvature will be affected by frictional force.
Here, is magnitude of frictional force.
