Final answer:
To find the values of u, v, and w that satisfy the equation -3u - 7v - w = 0, follow these steps: identify the knowns, identify the unknown, choose the equation u = -3u - 7v - w, and plug in the known values.
Step-by-step explanation:
Solution for (b)
1. Identify the knowns. v=0.500c; u' = -0.750c
2. Identify the unknown. u
3. Choose the appropriate equation. u = -3u - 7v - w
4. Plug the knowns into the equation.
