Two particles of same mass m moving with velocities `u_(1)` and `u_(2)` collide perfectly inelastically. The loss of energy would be :

Options

A. `1/2 m(u_(1) - u_(2))^(2)`
B. `1/4 m(u_(1) - u_(2))^(2)`
C. ` m(u_(1) - u_(2))^(2)`
D. ` 2m(u_(1) - u_(2))^(2)`

Answer

`(2)`

Explanation

`Delta KE = (m_(1)xx m_(2))/2(m_(1) + m_(2))[u_(1) - u_(2)]^(2)`
