B is a stationary observer. I am trying to calculate how fast object A is approaching B, even though object A is moving towards the origin.
I haven't been in a physics class since college, but remember that it probably has something to do with the law of cosines. I don't think it is just a...
I want to calculate the instantaneous relative velocity between two objects. Object A is at location (x1,y2) moving towards the origin (0,0) at velocity V. How do you calculate object A's relative velocity to object B at location (x2,y2)?
