Problem 4: A jet airliner movin
102 mi/h in a
nitiaily at 3.00 x 102 mi/h due east enters a region where the wind is blowing 1.00 x
30 0° north of east.
a)
Find th components of the velocity of the jet airliner relative to the air, VA
b) Find the components of the velocity of the air relative to Earth,
c)write an equation relating the velocities
d)What are the speed and direction of the aircraft relative to the ground?

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
