Question

Find a vector in the direction of with magnitude 3.

Short answer

The required vector is.

Step-by-step solution

Step 1. Given information.

The given vector is:

with magnitude 3.

Step 2. Find the norm of the vector.

Therefore, the norm of the given vector is $\sqrt{14}$.

Step 3. Find the vector.

We know that the vector in the direction of vis $\frac{a}{||\mathit{v}||}\mathit{v}$. Here ais the magnitude of the given vector.

The required vector is:

Therefore, the vector in the direction of and with a magnitude of 3 is .
