Answer: The mass is 4kilograms

Explanation:

Kinetic energy = 1/2 X (Mass X Velocity*2)

18 = 0.5 X Mass X 3*2

18 = 0.5 X Mass X 9

18 = 4.5 X Mass

Mass = 18/4.5

Mass = 4kg

When a lunar eclipse happens, which would we not see: the sun or the moon?
Nookie1986 [14]

Answer:

the sun

Explanation:

The typical lunar eclipse happens when the Sun, Earth and moon are all aligned 180 degrees apart from each other in the sky. When this happens, the Earth casts a shadow onto the moon, so the Sun should not be visible at all if you can still see the moon.
