Objects A and B are at the origin. If object A moves to #(6 ,7 )# and object B moves to #(-1 ,3 )# over #4 s#, what is the relative velocity of object B from the perspective of object A?
First, use the Pythagorean Theorem, then use equation
Object A has moved
Object B has moved
The velocity of Object A is then
The velocity of Object B is then
Since these objects are moving in opposite directions, these velocities will add, so they will appear to be moving at 3.10 m/s
away from each other.
