4. Steps to find the relative velocity Let the object be moving with velocity V1 andthe observer be moving with velocity v2. To find the relative velocity of object with respect to observer follow the following steps-

5. (i) Reverse the velocity of the observer. (ii) Superimpose the velocity of object upon reverse velocity of observer. So we obtain Vr V1-V2 (iii) Resultant velocity will be the relative velocity That is

6. Two particles start from rest simultaneously and are equally accelerated. Throughout the motion, the relative velocity of one with respect to other is: (A)zero (B) non zero and directed parallel-to acceleration (C) non zero and directed opposite to acceleration (D) directed perpendicular to the acceleration

7. They will have the same velocity at all t instants and hence their relative velocity is zero

8. Two particles are moving with velocities v1 and v2 Their relative velocity is the maximum, when th angle between their velocities is: (A)Zero (B)n/4 (C)T/2 (D)

9. When the particles, move in opposite directions, relative velocity is Vi+ V2

10. Two particles P1 and P2 are moving with velocities v and v2 respectively. Which of the statement about the relative velocity Vr12 is true? (A)Vr12 cannot be greater than vi+V2 (B) Vr12 cannot be greater than vr-V2 (C) Vr12 > (Vi + V2) r12

11. The relative velocity of a particle moving with a velocity v, with respect to itself is: (A)Zero (C) -v (B) v (D) none of the above
