Vectors Test 2 – Review

Bring a straight edge for use during the test

1. Review Set 3 problems.  Solve both types of “river” problems, a “hammock” problem, and a “sign on the wall” problem. You must construct diagrams of the tension vectors before and after transposition.
2. Solve both types of "jet" problems.  Refer to Example 3-10 in the text.
3. Know how to apply the Law of Sines, and be able to establish F_T, and angles theta, 2-theta, and phi.
4. Know how to diagram a reference scalar triangle and a reference vector triangle for a relative velocity problem.
5. Compare and contrast the tension in each half of a wire supporting a picture on a wall and the tension in each half of a hammock.
6. Compare and contrast V_B,E, V_B,R, V_R,E when solving a “river” problem.
