Relative Velocity|Questions

The vector difference between the absolute velocities of two bodies is called their relative velocity. The concept of relative velocity enables us to treat one body as being at rest while the other is in motion with the relative velocity. This jormalism greatly simplifies many problems. If vecv_(A) is the absolute velocity of a body A and vec_(B) that of another body B then the relative velocity of A in relation to B is vec_(AD)=vecV_(A)-vecv_(B) and vecv_(BA)=vecv_(B) - vecv_(A) . The principle follows here is that the relative velocity of two bodies remains unchaged if the same additional velocity is imparted to both the bodies. A simple way of carrying out this operation is to be represent the velocities in magnitude and direction from a common point. Then the line joining the tips of the vectors represents the relative velocity Q A train A moves to the east with velocity of 40 km/hr and a train B moves due north with velocity of 30 km/hr. The relative velocity of A w.rt. B is

Problems on Relative Velocity of Rain and Woman

Assertion : The sound emitted by the source travels in all directions. Reason : The relative velocity of sound with respect to the observer is the sum of velocity of sound and velocity of observer.

Define relative refractive index in terms of velocity of light.

In perfectily inelastaic collition the relative velocity of the bodies

In two separate collisions, the coefficient of restitutions e_(1) and e_(2) are in the ratio 3 : 1 . In the first collision the relative velocity of approach is twice the relative velocity of separation. Then, the ratio between relativevelocity of approach and relative velocity of separation in the second collision is
