Two identical mass M moving with velocity u_1 and u_2 collide perfectl

1.	Two identical mass M moving with velocity u_1 and u_2 collide perfectly inelastically. The loss in kinetic energy is
Answer» `M/2 (u_2 - u_1)^2` `M/2 (u_1^2 - u_2^2)` `M/4 (u_2 - u_1)^2` `M/4 (u_1^2 - u_2^2)` Solution :LOSS in kinetic ENERGY in a perfectly inelastic COLLISION is `DELTA K = 1/2 (m_1m_2)/((m_1 + m_2)) (u_1 - u_2)^2` Here, `m_1 = m_2 = M` `:. Delta K = 1/2(M XX M)/((M + M)) (u_1 - u_2)^2 = M/4 (u_1 - u_2)^2` .
