A car is traveling east at 14m/s, weighing 2000kg. A car is traveling north at an unknown velocity, and weighs 1500 kg. Upon collision, the cars join as one, and skid together at a northeast direction that is measured at 50 degrees above the horizontal.
What is the speed of the car traveling north.
