1.	An object A is moving with 5m/s and B is moving with 20m/s in the same direction. (Positive x-axis). Find (a)velocity of B relative to A. (b) Velocity of A realtive to B.
Answer» SOLUTION :(a)`vecV_(B)=20hat(i)"m/s" , vecV_(A)=5hat(i)"m/s",` `vecV_(B)-vecV_(A) = 15hat(i)`m/s `vecV_(B)=20hat(i)"m/s", vecV_(A)=5hat(i)`m/s, `vecV_(AB)=vecV_(A)-vec_(B)=-15hat(i)`m/s
