Given that,
Mass of trackler, m₁ = 100 kg
Speed of trackler, u₁ = 2.6 m/s
Mass of halfback, m₂ = 92 kg
Speed of halfback, u₂ = -5 m/s (direction is opposite)
To find,
Mutual speed immediately after the collision.
Solution,
The momentum of the system remains conserved in this case. Let v is the mutual speed after the collision. Using conservation of momentum as :
![m_1u_1+m_2u_2=(m_1+m_2)V\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\V=\dfrac{100\times 2.6+92\times (-5)}{(100+92)}\\\\V=-1.04\ m/s](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3D%28m_1%2Bm_2%29V%5C%5C%5C%5CV%3D%5Cdfrac%7Bm_1u_1%2Bm_2u_2%7D%7B%28m_1%2Bm_2%29%7D%5C%5C%5C%5CV%3D%5Cdfrac%7B100%5Ctimes%202.6%2B92%5Ctimes%20%28-5%29%7D%7B%28100%2B92%29%7D%5C%5C%5C%5CV%3D-1.04%5C%20m%2Fs)
So, the mutual speed immediately after the collision is 1.04 m/s but in opposite direction.

Answer: 1 dioptre of power of a lens is defined as the unit of measuring the power of optical lens Or curved mirror which is equal to the reciprocal of the focal length. The focal length is measured in the meter. 1 dioptre is equal to 1/m where m is the focal length. Basically dioptre is the SI unit of optical power of the lens.
