Momentum (p) = mass × velocity
P= 200,000×4.5
P= 900,000 .... answer !!
I think it is B, because the sun’s size is pretty average
The pet store would be the reference point because it is where he started and it will not move. Hope this helped.

Therefore, k = F / ∆x = 250 / 0.2 = 1250 N/m
(ps: convert 20 cm into 0.2 m)
