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

D edge

Answer 2

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

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`
