Objects A and B are at the origin. If object A moves to #(-2 ,7 )# and object B moves to #(6 ,-5 )# over #3 s#, what is the relative velocity of object B from the perspective of object A? Assume that all units are denominated in meters.
Initially both A and B were at origin O (0,0)
after 3sec A reaches at (-2,7) and B at (6,-5)
So displacement vector of A =
velocity vector of A,
displacement vector of B =
velocity vector of B,
So the relative velocity of B from the perspective of A is given by
