Question

An airplane's velocity is represented by the vector p = 30i-492j+42k. There is a crosswind of velocity t=19j-45k. Use this information to determine the vector which represents the velocity of the airplane when it is affected by the wind.

Answer 1

Answer:$30 i -473 j -3 k$

Step-by-step explanation:

We are given two velocity vectors with its three components in unit notation:

Airplane's velocity:

$\vec{p}=30i-492j+42k$

Crosswind velocity:

$\vec{t}=0i+19j-45k$

Now, if we want to know the velocity of the airplane when it is affected by the wind, we have to add these two velocity vectors:

$\vec{p} + \vec{t}=(30i-492j+42k) + (0i+19j-45k)$

Adding both vectors:

$\vec{p} + \vec{t}=30i-473j-3k$
