Решение задачи по физике раздел 50 пункт 87 механика

87. In central perfectly elastic collision moving body mass m1 hits the stationary body weight m2, bringing the speed of the first body decreases n = 1,5 times. To determine: 1) the ratio of m1 / m2; 2) kinetic energy T2 of the second body, if the initial kinetic energy of the first body T1 = 1000 J.
