Determine what was the initial speed of the lighter car

Reference no: EM13535014

A 900- 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 30.0 km/h in a direction of 40 o with respect to the positive x axis. The heavier car moves at 33 km/h at -46 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)?
