there is a apollo space craft that took astronauts to the moon. the space craft weighed about 5 million pounds with motots that produced 7 million pounds of thrust.
which statement explains how the spacecraft left the surface of earth.
A. the space craft applied a downward force of thrust that was less than the downward force of gravity.
B. the space craft applied a downward force of thrust that was equal than the downward force of gravity.
C.the space craft applied a upward force of thrust that was equal than the downward force of gravity.
D.the space craft applied a upward force of thrust that was gravity than the downward force of gravity.
C. The space craft applied an upward force of thrust that was equal to the downward force of gravity.
The correct statement that explains how the spacecraft left the surface of Earth is:
C. The spacecraft applied an upward force of thrust that was equal to the downward force of gravity.
To determine which statement explains how the spacecraft left the surface of the Earth, we need to consider the forces involved.
In this scenario, we have two main forces: the force of gravity pulling the spacecraft downwards and the thrust force generated by the spacecraft's motors pushing it upwards.
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the motors of the spacecraft generate a thrust force pushing it upwards, and as a result, there is an equal and opposite force pushing downwards.
Given that the thrust generated by the motors is 7 million pounds and the weight of the spacecraft is 5 million pounds, we can conclude that the downward force of the thrust is greater than the downward force of gravity.
Therefore, the correct statement explaining how the spacecraft left the surface of the Earth is:
D. The spacecraft applied an upward force of thrust that was greater than the downward force of gravity
