The Wind Direction at Minneapolis

Analysis of Wind Direction

Explanation: To determine the direction from which the wind is coming, we analyze the given information about the airplane's velocity and the wind's effect on it. In the scenario provided, an airplane that is known to be heading north has a resultant velocity of 38.0 m/s directed west of north. This implies that the wind is blowing from the northeast, toward the west and south, causing the airplane to slow down and deviate from its intended northern course. Figure 3.44 in the question supports this analysis by describing the plane's velocity with respect to the ground and indicating that the wind affects its movement. Therefore, the wind reported at Minneapolis that makes a plane travel north at 45.0 m/s slow down and shift direction would be generally from the northeast.
