​A football player weighing 110 kg and traveling at +6 m/s runs head on into another player who weighs 150 kg and is traveling a
Schach [20]

This is an <em>inelastic </em>collision. The equation for an inelastic collision is: m_{1}v_{1}_{i} + m_{2}v_{2}_{i} = (m_{1} + m_{2})v_{f}

(110)(6) + (150)(-4) = (110 + 150)(vf)

660 - 600 = 260vf

60 = 260vf

vf = 0.2308 m/s

They will travel in the positive direction, right, and their combined velocity will be 0.2308 m/s.

Hope this helps!! :)

Which of the following remains constant for a satellite in an elliptical orbit.
Softa [21]

If the satellite doesn't have little rocket engines or other thrusters on it, AND it stays far enough from Earth that it doesn't have to plow through any air molecules, AND no pieces break off of it and drift away, AND there are no hamsters inside it running on treadmills connected to external thrusters, then there's no way for it to gain or lose energy, and its total energy remains constant.  

Some of its energy is always changing, either from potential to kinetic or from kinetic to potential, as its distance from Earth changes.  But the total stays constant.

Answer:

Asteroids

Explanation:

Asteroids are the small and large block of rocks that are found to be scattering space. There are numerous asteroids present in the asteroid belt which is located between the planet of Mars and Jupiter. These range from a  few meters to hundreds of kilometers. They move so rapidly, at about 80,000 km/hr and there occurs constant collision with one another. These asteroids sometimes enter into the atmosphere of earth, which can cause a great mass extinction event.

These are believed to be the remnants particles that are present in space right after the formation of the solar system.
