Revolt · Accepted Answer

A: cap n 30 degrees cap e

Question 2

A plane is traveling with an airspeed of 350 mph in the direction cap n 40 degrees cap e Let the plane’s ground speed equal x , which is affected by a 50 -mph wind blowing directly from the south. Which diagram represents this scenario?

Revolt · Accepted Answer

C: Image with description On a coordinate plane, a vector labeled 350 miles per hour is 40 degrees from the y-axis in quadrant 1. Vector x is about 35 degrees from the y-axis. A vector labeled 50 miles per hour connects the terminal points of the 2 vectors.
