An isolated particle of mass m is moving in horizontal in horizontal plane (x-y) along the x-axis at a certain height above the ground. It suddenly explodes into two fragments of masses m/4 and 3m/4. An instant later, the smaller fragment is at y = +15 cm. The larger fragment at this instant is at

The center of mass, according to the principle of conservation of momentum, remains unchanged if no external forces act on the system. The particle breaks into two fragments, one with aRead more
The isolated particle of mass m is moving horizontally along the x-axis and suddenly explodes into two fragments. The center of mass, according to the principle of conservation of momentum, remains unchanged if no external forces act on the system. The particle breaks into two fragments, one with a mass of m/4 and the other with a mass of 3m/4.
Given after the explosion that the smaller fragment is located at y = +15 cm, use the idea that the overall center of mass for the system must remain at the same vertical position as before the explosion, which was at y = 0.
The position of the center of mass is determined by the masses and their respective positions. Since the smaller fragment is at y = +15 cm, the position of the larger fragment must be such that it balances this position according to their mass ratio. By conservation, we determine that the larger fragment must be positioned at y = -5 cm. This negative position denotes that it lies below the initial center of mass level, making sure the global system maintains the center of mass position after detonation.

In Dvi Pāda Pavana Muktāsana, lie in a supine position. Inhale to raise both legs to 90°, then exhale to pull knees to the chest, holding them with interlocked hands. Inhale to release the knees and stretch legs. This sequence improves digestion, reduces abdominal gas, and strengthens the abdominalRead more
In Dvi Pāda Pavana Muktāsana, lie in a supine position. Inhale to raise both legs to 90°, then exhale to pull knees to the chest, holding them with interlocked hands. Inhale to release the knees and stretch legs. This sequence improves digestion, reduces abdominal gas, and strengthens the abdominal and spinal muscles. Regular practice enhances flexibility and promotes better gastrointestinal health, making it an effective Yoga Kriya for physical well-being.
