Explanation:
Let m is the mass of both cars. The first car is moving with speed v and the other car is moving with speed 2v. The only force acting on both cars is the centripetal force.
For faster car on the road,
v = 2v
..........(1)
For the slower car on the road,
............(2)
Equation (1) becomes,
So, the frictional force required to keep the slower car on the road without skidding is one fourth of the faster car.
Answer:
Yes, a body with a certain velocity can have an opposite acceleration, the acceleration would then be negative, since it is opposite to the direction to the velocity and also because the direction in which the acceleration is portrayed is on the left-hand side.
Hope this answer helps :)
