To solve the problem, we need to determine the minimum time required for a car to cover a distance of 400 meters on a rough horizontal road, given that the coefficient of friction (μ) is 0.4. The car starts from rest and eventually comes to rest. ### Step-by-Step Solution: 1. **Identify the Given Data:** - Coefficient of friction, μ = 0.4 - Distance to be covered, S = 400 m - Initial velocity, u = 0 m/s (the car starts from rest) ...

A block of mass m moving with a velocity v_(0) on a rough horizontal surface from x=0 coefficient of friction is given by mu=mu_(0)+ax . Find the kinetic energy of the block as function of x before it comes to rest.

Choose the correct option: A small collar of mass m is given an initial velocity of magnitude v_(0) on the horizontal circular track fabricated from a slender rod. If the coefficient of kinetic friction is mu_(K) , determine the distance traveled before the collar comes to rest. (Recognize that the friction force depends on the net normal force).

A block of mass m starts at rest at height on a frictionless inclined plane. The block slides down the plane, travels across a rough horizontal surface with coefficient of kinetic friction mu and compresses a spring with force constant k a distance x before momentarilly coming to rest. Then the spring extends and the block travels back across the rough surface, sliding up the plane. The block travels a total distance d on rough horizontal surface. The correct experssion for the maximum height h' that the block reaches on its return is :

The coefficient of friction between the tyres and road is 0.4. The minimum distance covered before attaining a speed of 8 ms^(-1) starting from rest is nearly ( take g=10 ms^(-2) )

A point particle of mass m, moves long the uniformly rough track PQR as shown in figure. The coefficient of friction, between the particle and the rough track equals mu . The particle is released, from rest from the point P and it comes to rest at a point R. The energies, lost by the ball, over the parts, PQ and QR, of the track, are equal to each other, and no energy is lost when particle changes direction from PQ to QR. The value of the coefficient of friction mu and the distance x (=QR) , are, respectively close to:
