Question

An airplane is traveling due east with a velocity of 7.5 × 102 kilometers/hour. There is a tailwind of 30 kilometers/hour. What is the value of the resultant velocity of the airplane?

Answer 1

a tailwind means you add thed velocity of the tailwind to the velovity of the plane (no need for any vectors etc. so you just need (7.5x 102 ) +30 then convert it so it like one of the answers (btw - none of the answers is exactly correct - you need to round to get it) thats what you need to do to get the question

Answer 2

`7.5* 10^(2) \dotplus 30 = 7.8 * 10^(2) km h^(-1)`

Step-by-step explanation:

The air plane is traveling towards East. The tail wind is the wind which is in the same direction as that of the plane's velocity direction. That's why the net velocity or the resultant velocty is the sum of the velocity of the plane and the tail wind velocity.
