Their velocity after the collision was 2 m/s.
What is principle of conservation of momentum?
According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Given parameters:
one player (m=100kg) was moving at a velocity of 8 m/s initially.
Another player (m=300kg) who was at rest (v=0m/s) initially.
After collision they stuck together and let the velocity of them is v.
According to principle of conservation of momentum, total momentum remains conserved.
total initial momentum = total final momentum
100×8 + 300×0 = (100 + 300)v
400v = 800
v = 2.
Hence, their velocity after the collision was 2 m/s.

How does the digestive system interact with the following organ systems (circulatory, muscular and nervous system) to maintain homeostasis?
Answer:
The circulatory system breaks down food and gets / absorbs nutrients. The muscular system works to get nutrients to the rest of the body. The nervous system basically controls the digestive system and sends information to the brain.
