Consider the collision of a 1500-kg car traveling east at 20. 0 m/s (44. 7 mph) with a 2000-kg truck traveling north at 25 m/s (55. 9 mph). The cars lock together in such a way as to prevent them from separating or rotating significantly. One second before the collision, the car is located at position (x, y) = (-20,0)~\text{m}(x, y)=(−20,0) m and the truck is located at position (x, y) = (0,-25)~\text{m}(x, y)=(0,−25) m.
