Two object A and B are moving each with velocities 10 m/s. A is moving towards East and B is moving towards North from the same point as shown. Find velocity of A relative to B `(vecV_(AB))`

Text Solution

Verified by Experts


`vecV_(AB)=vecV_(A)-vev_(B)=10i-10 j`
`|vecV_(AB)|=sqrt(10^(2)+10^(2))=10 sqrt(2)ms^(-1)` along SE
