It could never actually happen like this, but the question is
looking for you to 'conserve' the momentum.
Momentum of a moving object is (mass) x (velocity).
Like velocity, momentum has a direction.
Momentum is one of those things that's 'conserved'.
That means that momentum can't appear out of nowhere, and
it doesn't disappear. The total after the collision is the same as
the total was before the collision.
Momentum of the skinny player:
(70 kg) x (3 m/s north) = 210 kg-m/s north.
Momentum of the heavy player:
(80 kg) x (1.5 m/s south) = 120 kg-m/s south .
Total momentum before the collision is
(210 kg-m/s north) + (120 kg-m/s south)
= 90 kg-m/s north .
It has to be the same after the collision.
(mass) x (velocity) = 90 kg-m/s north.
The mass after the collision is 150 kg, because they get
tangled up and stuck together, and they move together.
(150 kg) x (velocity) = 90 kg-m/s north .
Divide each side
by 150 kg : velocity = (90 kg-m/s north) / (150 kg)
= (90/150) (kg-m/s / kg north)
= 0.6 m/s north .
Answer: If the speed of an object changes, it will be accelerating or decelerating . This can be shown as a curved line on a distance-time graph.
Explanation:
The results of the experiments should be similar.

Expalantion</h2>
In the ancient time, the scientists believed that there is the smallest particle which can control the nature of reaction in the environment which they called them. Then a lot of experiment was conducted in which new coming scientists discovered the protons, electrons, neutrons, and other smallest particles. Firstly, scientists performed experiments for this new discoveries to know better about them and then include them in their next experiment for better exposures.
