3. A car with mass 1.39 X 10' kg traveling east at a speed of 27.0 m/s collides at an intersection with a 3.00 X 10'-kg van traveling north at a speed of 22.0 m/s. Find the (a) magnitude and (b) direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected. (10 pts.) + 27.0 m/s + 22.0 m/s
