In this problem, we have been given that there is a circular highway and a vehicle which is passing through this bend is moving at a speed of 64 kilometers per hour.
00:13
That means the speed here when we convert in meter per second, we just multiply the given speed in kilometers per hour with 5 by 18 and that gets us the speed at 17 .8 meter per second approximately.
00:28
So the truck here, the vehicle is moving at a speed of 17 .8 meter per second.
00:36
Considering the radius of this curve as approximately 213 meters, here we need to determine the coefficient of friction that should be present between the tires and the road that will allow the vehicle to turn safely without skidding.
00:55
Also here it's given that the traffic in a rainy day, that moves at a speed of 44 kilometers per hour.
01:06
So when we convert that speed 44 kilometers per hour into meter per second, we again multiply 44 with 5 by 18, and that gets us the speed as 12 .2 meter per second approximately.
01:21
So let's figure out the safe speed with which the car can turn without skating.
01:25
So if you observe the free body diagram, the friction force here will be towards the center and that will be responsible for providing the necessary sentry petal force...
