It would mean that only one side of earth would be light and the other dark all the time also we would only see the sun on one side and on the other we see the moon
Answer:
Speed of another player, v₂ = 1.47 m/s
Explanation:
It is given that,
Mass of football player, m₁ = 88 kg
Speed of player, v₁ = 2 m/s
Mass of player of opposing team, m₂ = 120 kg
The players stick together and are at rest after the collision. It shows an example of inelastic collision. Using the conservation of linear momentum as :
![m_1v_1+m_2v_2=(m_1+m_2)V](https://tex.z-dn.net/?f=m_1v_1%2Bm_2v_2%3D%28m_1%2Bm_2%29V)
V is the final velocity after collision. Here, V = 0 as both players comes to rest after collision.
![v_2=-\dfrac{m_1v_1}{m_2}](https://tex.z-dn.net/?f=v_2%3D-%5Cdfrac%7Bm_1v_1%7D%7Bm_2%7D)
![v_2=-\dfrac{88\ kg\times 2\ m/s}{120\ kg}](https://tex.z-dn.net/?f=v_2%3D-%5Cdfrac%7B88%5C%20kg%5Ctimes%202%5C%20m%2Fs%7D%7B120%5C%20kg%7D)
![v_2=-1.47\ m/s](https://tex.z-dn.net/?f=v_2%3D-1.47%5C%20m%2Fs)
So, the speed of another player is 1.47 m/s. Hence, this is the required solution.
