Explanation:
In a weightless environment a force of 5 Newtons is applied horizontally to the right on a rock with a mass of 1 kg and to a pebble with a mass of 0.1 kg.
Answer:
Mass of receiver is 92 kg
Explanation:
We have given mass of tackler ![m_1=100kg](https://tex.z-dn.net/?f=m_1%3D100kg)
Let the mass of receiver is ![m_2kg](https://tex.z-dn.net/?f=m_2kg)
When tackler moving alone velocity is
m/sec
And when tackler and receiver is together velocity is
= 2.5 m/sec
So from conservation of momentum
![m_1v_i=(m_1+m_2)v_f](https://tex.z-dn.net/?f=m_1v_i%3D%28m_1%2Bm_2%29v_f)
![100\times 4.8=(100+m_2)\times 2.5](https://tex.z-dn.net/?f=100%5Ctimes%204.8%3D%28100%2Bm_2%29%5Ctimes%202.5)
![2.5m_2+250=480](https://tex.z-dn.net/?f=2.5m_2%2B250%3D480)
![2.5m_2=230](https://tex.z-dn.net/?f=2.5m_2%3D230)
![m_2=92kg](https://tex.z-dn.net/?f=m_2%3D92kg)
So mass of receiver is 92 kg
