The closest is the one we're in. We call it the Milky Way galaxy.
The nearest one outside of the Milky Way is the Andromeda galaxy ... less than a piffling 3 million light years away, practically in our back yard.
Answer:
Given:
mass of the ball m = 0.144 kg
velocity v = 38 m/s
now, change in momentum
P = m v- ( - mv)
= 2 mv
=2 x (0.144) x (38)
= 10.944 kg-m/s
Impulse J= F. Δt
change in momentum is equal to impulse
J = 10.944 kg-m/s
we know force is equal to change in momentum per unit time


F = 13.68 x 10³ N
F = 13.68 kN
Mantle I think idrk cuz of erosion
Where are the images?!?!?
