In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?
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.

A pair of point charges, which have charges of –3µ C and –4µ C are separated by 2 cm. What is the value of the force between them
Answer:
pk
Explanation:
Earth's subsystems are the geosphere, atmosphere, hydrosphere, and biosphere. Energy and matter are transferred when Earth's subsystems interact.
Describe which of Earth's subsystems are involved when a hurricane passes through an area. Explain how these different subsystems affect one another.
Answer:
ok
Explanation:
The Earth is made of several subsystems or "spheres" that interact to form a complex and continuously changing whole called the Earth system. Scale
Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.
Examples of instantaneous - breathing; rotation of the Earth; earthquake
Examples of long term - making coal; plate tectonics
Cycles
The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.
Examples of cycles: day and night; rock cycle; seasons
Energy
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
Humans and the Earth System
People are part of the Earth system and they impact and are impacted by its materials and processes.
