A 800- kg car collides with a 1400- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 20.0 km/h in a direction of 40 o with respect to the positive x axis. The heavier car moves at 23 km/h at -42 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)?

A car of mass 950 kg travelling north at 50 km/h collides with a car of mass 1350 kg going south at 45 km/h in a completely inelastic collision (i.e. they stick together). Determine the velocity of the car/car combination immediately after the collision. (North is the positive direction and south is the negative direction.) km/h

A car of mass 1478 kg collides head-on with a parked truck of mass 2000kg. Spring mounted bumpers ensure that the collision is essentially elastic. If the velocity of the truck is 17 km/h (in the same direction as the car's initial velocity) after the collision, what is the initial speed of the car?
