Final answer:
The weight of the stone is 49 N.
Step-by-step explanation:
The weight of an object is equal to its mass multiplied by the acceleration due to gravity.
The principle also applies to both classical and modern physics, indicating its broad importance across different scales and realms of physical inquiry, from the motion of galaxies to the interactions of quarks within protons and neutrons.
In this case, the mass of the stone is 5 kg and the acceleration due to gravity is 9.8 m/s².
Momentum is not only conserved in mechanical systems but is also fundamental to understanding the behavior of both massive and massless particles, such as photons.
Therefore, the weight of the stone is 5 kg * 9.8 m/s² = 49 N.
