    Calculating Velocity Vector of Object in 2D Space

    I have these equations for the two points … ##x_1 = r_1 cos(\theta_1)## ##y_1 = r_1 sin(\theta_1)## ##x_2 = r_2 cos(\theta_2)## ##y_2 = r_2 sin(\theta_2)## This is the slope ##\frac {(y_1 – y_2)}{ (x_1-x_2)}##From the point slope formula ##y – y_1 = \frac {(y_1 – y_2)}{ (x_1-x_2)} (x –...

    Calculating Velocity Vector of Object in 2D Space

    OK, thanks for the hints. I will work on what you suggest. FYI, we do know the angles. I don't know if this is useful or not. It would actually be better if I can solve the problem using one radial velocity

    Calculating Velocity Vector of Object in 2D Space

    The question I am trying to solve is what is the velocity vector (direction and magnitude) of an object in 2 d space. We know the distance measured to the car from two different angles. We know the radial velocity of the car on both measurements. The radial velocity is the component of the...
