Homework Statement
There are two cars traveling in a same direction. The Second car has a camera mounted on it and has ability to give relative X and Y (in meters) distance of first car with respect to it. Given the Speed of Second car , Calculate the Speed and Acceleration of first car. The First car gives relative x and y distances for every 0.01 seconds.
Homework Equations
Differentiation of distance gives velocity and double differentiation of distance gives me acceleration
The Attempt at a Solution
Vx = (x2-x1)/(t2-t1) ; t2-t1 is 0.01 seconds
; x2 is the X distance at second time instant and x1 is at first time instant
Vy = (y2-y1)/(t2-t1)
Speed = Sqrt(Vx^2 + Vy^2)
Ax = (Vx2 – Vx1)/ (t2-t1)
Ay = (Vy2 – Vy1)/ (t2-t1) I am not considering the Speed of Second vehicle at all... I think that's where I am getting wrong results. As camera gives me the relative x and y , and since camera itself is moving , Do I need to add the Speed to Vx and then compute acceleration >?
