The rocket will shoot from the moon at a velocity of 0.39 m/s, in accordance with the question.
What is a massive example?
The mass of matter that makes up every item or body is the simplest way to understand mass. Every that we can see has mass.
F=ma
First Law of Motion (remember this equation)
28500 = 13800 * a
(Kg is the measurement of mass, while N is a measure of force.)
calculate a
In empty space, the velocity would be at a = 2.06 m/s2, but the moon is pulling it down.
We deduct it from acceleration because downward motion is the direction in which the item is traveling.
2.06-1.67 = 0.39
Consequently, the rocket will ascend at 0.39 m/s.
