Vectors are fair game in Alg 2/Trig as Law of Sines/Cosines application problems, and we get one measly day to spend on it. Not an issue for kids who are taking Physics concurrently, but we don't get many of those since Alg2/Trig is sophomores and juniors. With 42 minutes I couldn't come up with a manageable way to use those static spring loaded pull scale things the physics teachers have.
