Question

Consider a plane traveling with a velocity of 100km/hr, south that encounters a side wind of 25km/hr west.

A. Draw a vector diagram
B. Find the magnitude and position of believing city of a plane using Pythagorean theorem​

Answer 1

To solve this. think of it as a simple right triangle. One line of the triangle points south, and the other side line of the triangle points west. the hypotenuse connects the line going south, and the line going west. now label it.

South line, is 100km/hr

west line, is 25km/hr.

Remember A^2+B^2=C^2? use that.

100^2+25^2=10,625.

where 10,625 is C^2.

take the square root. you get

103.07764km/hr

or just 103km/hr
