66. Ball m1 = mass of 2 kg hits the ball resting mass m2 = 8 kg. Momenta p1 moving ball is 10 kg • m / s. Hit balls straight elastic. To determine immediately after the impact: 1) pulses p1 'of the first ball and p2' second ball; 2) a change in the momentum Δp1 first ball; 3) the kinetic energy of T1 'first ball and T2' second ball; 4) change ΔT1 kinetic energy of the first ball; 5) share ω of kinetic energy transferred to the first ball of the second.
