Answer:
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... The momentum of a body is equal to the product of its mass and its velocity.
Answer: 17.14 m/s
Explanation:
We can solve this problem applying the Conservation of Mechanical energy (which is the sum of the kinetic energy and potential energy ), where the total initial mechanical energy must be equal to the total final mechanical energy :
(1)
Being:
(2)
(3)
Where:
is the mass of the object
is the initial velocity (the object was at rest)
is the acceleration due gravity
is the object's initial height or position
is the final velocity
is the object's final height or position
Solving and applying the given conditions:
(4)
(5)
Finding :
(6)
(7)
Finally:
Freezing since the molecules are coming closer togther
Answer:
gravity is something that makes things go up and down
Explanation:
the motion is sensible
Answer:
Matter is made of atoms which are in turn made up of protons, nuetrons and electrons. Atoms come together to form molecules which is the building block for all matter.
Explanation:
I feel like this question is like What is the meaning of life. Matter is made up of Matter. i don't know man
