Michael was late for work once again. He raced at his maximum running speed of 6 m/s toward the bus stop where the bus was already waiting. To his dismay, the
bus started to accelerate uniformly away from the bus stop at 1 m/s 2 just as Michael
was a mere 25 m away.
“Oh no, not again!” he yelled out as he continued onward.

(a) Plot a position time graph of the motion of Michael and the bus on the same
set of axes. Plot from t = 0 s to t = 10 s.
(b) From the above graph, determine if Michael would catch up to the bus. If
not what was his closest approach?
(c) Now solve the problem algebraically.

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.
