2. attached picture

3. Could a vector ever be shorter than one of its components? Could a vector ever be equal in length to one of its components? Explain.

Answer 1

Answer:

D. is the correct answer.

Explanation:

We can use sin cos tan method to solve Mx:

$\frac{Mx}{5}=cos(37)$

$Mx= cos(37) * 5$

$Mx = 4$

So Mx should be 4 and head to right. as its positive.

We can use sin cos tan method to solve My:

$\frac{My}{5} = sin(37)$

$My = sin(37) * 5$

$My = 3$

So My should be 3 and head to upwards. as its positive.

Final conclusion: D. is the correct answer.
