The object with the greatest mass will have the most momentum to become equal with the other.
when we throw an arrow , we first stretch the string of the bow. while stretching the string of the bow, the work done by us in stretching the bowstring gets stored as potential energy in the bow. This potential energy of the bow is transformed into kinetic energy when the bowstring is released and this gives the momentum and Kinetic energy to the arrow.

Thomson atomic model was proposed by J.J Thomson in the year 1904 just after the discovery of electrons. According to the postulates of Thomson’s atomic model, an atom resembles a sphere of positive charge with electrons present inside the sphere. The positive and negative charge is equal and therefore an atom is electrically neutral. Thomson’s atomic model was compared to a spherical plum pudding as well as a watermelon. It was compared to a plum pudding because the electrons in the model look like the dry fruits embedded in a sphere of positive charge just like a spherical plum pudding. The model has also been compared to a watermelon because the red edible part of a watermelon was compared to the sphere having a positive charge and the black seeds filling the watermelon looked similar to the electrons inside the sphere.
#2 - A metal railing rusting in camp weather. Rusting is a chemical change.
Answer:
final displacement lf = 0.39 m
Explanation:
from change in momentum equation:
given: m = 0.4kg, y/x = 19/85, li = 1.9 m,
\delta p = 1.27 kg*m/s.
putting all value to get the final displacement value
final displacement lf = 0.39 m
