A S.S. automobile travels N at 40 km/h and a P.A. automobile travels E at 50 km/h. Relative to the observer riding in the S.S. auto what are the x and y components of the velocity of the P.A. car? The x axis is to the E and the y axis is to the N.
The x component of the PA/SS relative position is +50t km and the y component is -40t km.
t is the elapsed time in hours
