Задача 10656.

The shell emits from the gun vertically upwards, rises to a maximum height of h = 1000 m and is broken into two pieces of mass m1 = 1 kg and m2 = 2 kg. The larger fragment of m2 continues to move vertically upward, and the smaller m1 flies down. Calculate the velocity of the fragments in a time t = 1 s after the discontinuity, if their total kinetic energy immediately after the discontinuity was 120 kJ.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.

If you have any questions to address, please. I´ll try to help.
