Show that the kinetic immateriality of an motive having a majority m and momentum p is loving by K = p^2/2m. A majority m_1 traveling down the x-axis delay a expedite v rafteres a fully resolute clash delay a relieve majority m_2 that was moderately at quiet. Show that the aggregate kinetic immateriality exact succeeding the clash. K_f, is [m_1/(m_1 + m_2)]K_i, where K_i is the moderate kinetic of the arrangement. If a majority m_a = 2m has moderate rapidity 4 m/s and majority m_b = m is moderately at quiet, they rsucceeding alterable clash. Calculate their definite velocities succeeding the clash. If a majority m_a = 2m has moderate rapidity 4 m/s and majority m_b = m has moderately rapidity -6 m/s, they rsucceeding alterable clash. Calculate the definite velocities.
