A 1000-kg car traveling west at 30 m/s collides with a 1000-kg truck traveling south at 20 m/s. The occupants, wearing seat belts, are uninjured, but the two vehicles move away from the impact point as one. The insurance adjustor asks you to find the velocity of the wreckage just after impact. What is your answer?
