The concept used to solve this problem is the conservation of momentum and the conservation of energy.
For conservation of the moment we have the definition:
Where,
m = Mass
= Initial velocity for object 1
= Final velocity
Replacing the values we have to,
By conservation of energy we know that the potential energy is equal to the kinetic energy then
Therefore after the collision the height when the combined chinks will go is 1.837m
Minor characters. These are the other characters in a story. They are not as important as the major characters, but still play a large part in the story. Their actions help drive the story forward. They may impact the decisions the protagonist or antagonist make, either helping or interfering with the conflict.
Answer:
A. Here object is moving with increasing velocity
B. Here the object is moving with decreasing velocity that is it is decelerating
C. Here the initial and final velocity are the same so the object moves at constant velocity
D. Here the object started from rest but reached a certain velocity with time so a non zero acceleration was attained
The force of gravitational attraction between two objects is proportional to the sum of the two objects divided by their distance squared.
So if gravitation force increased, then either mass will proportionally increase or distance will proportionally decrease, or both.
