Suppose object A<span> is a cue ball and object </span>B<span> is an eight ball on a pool table. If the cue ball strikes the eight ball, the cue ball exerts a force on the eight ball that sends it rolling toward the pocket. At the same time, the eight ball exerts an equal and opposite force on the cue ball that brings it to a stop. Note that both the cue ball and the eight ball each experience a change in momentum. However, the sum of the momentum of the cue ball and the momentum of the eight ball remains constant throughout.</span>
Amount of molecules present in the substance
Explanation:
In general state of matter is classified into three types based on the amount of molecules present in the matter. They are widely classified as
SOLID
In solid the molecules are tightly packed without any free space to move inside. Therefore Solids have strong Inter-Molecular Force of attraction and have definite shape and volume.
LIQUID
In Liquid the molecules are not tightly packed. So that molecules move freely inside the matter. Therefore Liquids have Weaker Inter-Molecular Force of attraction and have no definite shape and no definite volume.
GAS
In Gas the molecules are loosely packed with more free space to move inside. Therefore Gas have the weakest Inter-Molecular Force of attraction and don't have definite shape and definite volume.
Momentum is mass times velocity and mass is measured in kg and velocity is measured per second so it really depends.
Kinetic energy is half the product of the mass and the square velocity and at highest point the velocity is 0 thus the kinetic energy is 0 J
Answer: 4.7rad
Explanation:
Angular displacement =s/r
Where s=distance traveled
r=radius
Angular displacement =141m/30m
Angular displacement =4.7rad.
