Two particles of masses `m_(1)` and `m_2` in projectile motion have velocities `vecv_(1)` and `vecv_(2)` respectively at time t = 0. They collide at time `t_(0)`. Their velocities become `vecv_(1)` and `vecv_(2)` at time `2t_(0)` while still moving in air. The value of `|(m_(1)vecv_(1) + m_(2)vecv_(2)) -(m_(1)vecv_(1) + m_(2)vecv_(2))|` is

Options

A. zero
B. `(m_1+m_2) "gt"_0`
C. `2(m_1+m_2)"gt"_0`
D. `1/2 (m_1 + m_2) "gt"_0`

Answer

C
