The point of science is to disprove wrong theories, and continue our knowledge forward that way. it's a lot easier to disprove something than to prove something as a rule has to fail once to be wrong, while you would have to prove and show that the rule works on every possible scenario for it to be proven, which is impossible. as such, a scientist should question current theories for faults, and confirm ( not prove) or disprove them.
Answer:
solution:
when the engine are fired the rocket has a linear constant acceleration motion:
is the final velocity of the rocket
when the engines are fired it become equal to the initial velocity of the rocket,
<em>when the engines are shut off</em>
<em></em><em></em>
solve eq(1) and eq(2) we find
solving for =364.65 m
Where is the distance travelled by the rockets for shutting off the engine
<em>when the engines are fired:</em>
<em></em><em></em>

Answer:
441J
Explanation:
Given parameters:
Mass of book = 5kg
Height = 9m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is given as:
Gravitational potential energy = mass x acceleration due to gravity x height
Gravitational potential energy = 5 x 9.8 x 9 = 441J
