Answer:

Explanation:
Essentially, Kinetic energy of the particle must equal the combined potential energies of earth and the moon when the object is on the moon's surface, meaning the full equation is
<h3>

</h3><h3 />
=Mass of Earth=
=Mass of Moon=
=distance from earth's center to the moon's=
=radius of moon=
After some algebra, the equation simplifies to

Plugging in the values of G, which is
, should yield the proper answer of 2780m/s.
Answer:
A) 580m
B) 0 m/s
C) 9.8m/s^2
D) downward
E) 10.87s
F) 106.62 m/s
Explanation:
A) The distance traveled by the rocket is calculated by using the following expression:

a: acceleration of the rocket = 2.90 m/s^2
t: time of the flight = 20.0 s

B) In the highest point the rocket has a velocity with magnitude zero v = 0m/s because there the rocket stops.
C) The engines of the rocket suddenly fails in the highest point. There, the acceleration of the rocket is due to the gravitational force, that is 9.8 m/s^2
D) The acceleration points downward
E) The time the rocket takes to return to the ground is given by:

10.87 seconds
F) The velocity just before the rocket arrives to the ground is:
