During that final period of time,
his acceleration is
(9 m/s - 5 m/s) / (4 sec) = 1 m/s² .
Did you have a question to ask ?
It’s a total of 16 cm because it starts at 0 moves then moves to left then the right then the left
Your answer would be A. Halogens

Explanation:
Newton's 2nd Law can be expressed in terms of the object's momentum, in this case the expelled exhaust gases, as
(1)
Assuming that the velocity remains constant then

Solving for
we get

Before we plug in the given values, we need to convert them first to their appropriate units:
The thrust <em>F</em><em> </em> is

The exhaust rate dm/dt is


Therefore, the velocity at which the exhaust gases exit the engines is


Answer:
Heat
Explanation:
Heat is the main component in why everything is not 100% efficient. Heat is a byproduct of everything and cannot be avoided.
