Question

Objects A and B are at the origin. If object A moves to `(-4 ,7 )` and object B moves to `(5 ,-3 )` over `4 s`, what is the relative velocity of object B from the perspective of object A?

Answer 1

`v_"AB"=3.36" "m/s`

`"angle="311.99^o`

Explanation:

`"displacement="13.45" "m`
`"time="4 s`
`"relative velocity="(13.45)/4`

`v_"AB"=3.36" "m/s`

`"angle="311.99^o`
