Question

Снаряд, летящий прямолинейно вверх, в высшей точке траектории разорвался на два осколка. Возможно ли, чтобы импульсы осколков в момент разрыва были равны по модулю и направлены горизонтально в противоположные стороны?

Answer 2

Can the impulses of the fragments be equal in magnitude and directed horizontally in opposite directions at the moment of explosion?

Yes, it is possible for the impulses of the fragments to be equal in magnitude and directed horizontally in opposite directions at the moment of explosion. When a projectile explodes, the conservation of momentum principle applies. According to this principle, the total momentum before the explosion is equal to the total momentum after the explosion, provided no external forces are acting on the system.

In the case of a projectile exploding at the highest point of its trajectory, the initial momentum is zero because the projectile is momentarily at rest. After the explosion, the two fragments will move in opposite directions. To satisfy the conservation of momentum, the magnitudes of their momenta must be equal but opposite in direction.

Therefore, it is possible for the impulses of the fragments to be equal in magnitude and directed horizontally in opposite directions at the moment of explosion.
