Question

Objects A and B are at the origin. If object A moves to `(-2 ,8 )` and object B moves to `(3 ,-3 )` over `4 s`, what is the relative velocity of object B from the perspective of object A?

Answer 1

`(5/4,-11/4)`

Explanation:

B's position with respect to A, at the end of 4 s is

`(3,-3) - (-2,8) = (5,-11)`

Since the initial relative position is `(0,0)` at `t=0`, we find the relative velocity of B with respect to A is

`1/4 (5,-11)`
