The frictional force is =1178.75N

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 10^{4} N.​

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 m =2000 kg

Speed v =10m/s

Radius of the path r=20 m

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.

f=\frac{mv^{2} }{r}

Here, f is magnitude of frictional force.

f=\frac{2000*10^{2}}{20}

f=10^{4} N
