A football coach walks 24 meters eastward, then 12 meters westward, then 36 meters eastward, and finally 22 meters
westward.
Whats the distance
Magnitude and direction

Distance magnitude = 24 meters

The direction of the displacement = Eastward

Explanation:

The distance walked by the football coach eastward = 24 meters

The distance walked by the football coach westward = 12 meters

Then the distance walked by the football coach eastward = 36 meters

Finally, the distance walked by the football coach westward = 22 meters

The total distance walked by the coach eastward  = 24 + 36 = 60 meters

The total distance walked by the coach westward  = 12 + 22 = 34 meters

Taking x-direction as positive, we have;

The magnitude of the distance = 60 - 34 = 24 meters,

The direction of the coach = Eastward.

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.
