What is the resultant velocity of a plane that is traveled at 245m/s, north and encounters a tailwind of 55m/s?

For this problem, you should use Pythagorean Theorem.

The formula for this is a^2 + b^2 = c^2.

The plane is moving north, and then moves to the right. Therefore, we need to find the hypotenuse, or resultant velocity. Plugging it into the equation we get, (245 m/s)^2 + (55 m/s)^2 = c^2

Solving for this, you will get 250 m/s.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
