Anjali's plane had been flying through calm skies (no wind) with a velocity (speed and direction) vector = (400,100). Now, however, the air mass surrounding the plane is moving quickly (i, it's windy). Although Anjali has not adjusted any of the controls in the cockpit, the plane's new velocity is = (350, 50). (Speeds are in kilometers per hour.) What is the speed of the wind?

The speed of the wind is 70.7 units.

Explanation:

The velocity of the wind is equal to plane's velocity before the wind minus its velocity after the wind:

Now, the speed of the wind is the magnitude of :

which is the speed of the wind.

P.S: No units are given for speed because no units were provided in the question.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
