A ball is thrown 6m above the ground. Its total energy at that point is 12 J. What is the total energy of the ball at a halfway point of motion

5.99 J

Explanation:

A ball is thrown 6m above the ground.

Its total energy at that point is 12 J.

The energy of the ball is given by :

E = mgh

Where

m is the mass of the ball

Let E' is the total energy of the ball at a halfway point of motion. h' = 3 m

So,

So, the required energy is 5.99 J.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

conservation of mass

mass before something happens = mass afterwards
