Question

In the square shown below, u is a unit vector. Find uv and uw.

a) uv = 0, uw = 0
b) uv = u, uw = u
c) uv = u, uw = 0
d) uv = 0, uw = u

Answer 1

To find the vectors uv and uw, you need to follow certain steps. By substituting the known values into the equation and combining like terms, you can determine the values of uv and uw.

Step-by-step explanation:

To find the vectors uv and uw, we need to follow these steps:

1. Identify the knowns: v = 0.500c and u' = -0.750c.
2. Identify the unknown: u.
3. Write the equation: u = v + u'.
4. Substitute the known values into the equation: u = 0.500c + (-0.750c).
5. Combine like terms: u = (-0.250c).
6. Therefore, uv = u = (-0.250c) and uw = u = (-0.250c).
