A 800- kg car collides with a 1300- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 15.0 km/h in a direction of 35 o with respect to the positive x axis. The heavier car moves at 18 km/h at -47 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)?  What was the initial direction (as measured counterclockwise from the x-axis)?
