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:
F= = 3.18 * 10^3 N
Explanation:
information given:
m= 40.5 kg
a= seven times gravity so we have
a= 7 g
where
gravity = g =9.8 m/s2
F= m*a
F= (40.5) * 7g
a = 7 g = (7) (9.8) = 68.6 m/s2
There are two forces acts on gymnsat
Where ,w is the weight of Gymnsat
F(net) = F - mg
F- mg = ma
F = mg+ma
so
F= m ( g + a)
F = (40.5) [9.8+ 68.6 ]
F = 3.18 * 10^3 N
The liquid decreases in temperature, and its particles lose kinetic energy.
