6 Two cyclists, A and B, have displacements 0 km and 70 km, respectively. At t=0 they
begin to cycle towards each other with
velocities 15 km h and 20 km h-',
respectively. At the same time, a fly that was
sitting on A starts flying towards B with a
velocity of 30 km h-'. As soon as the fly
reaches B it immediately turns around and
flies towards A, and so on until A and B meet.
(a) What will the displacement of the two
cyclists and the fly be when all three
meet?
(b) What will be the distance travelled by the
fly?

explanation:

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.
