This is only asking about one equation. This should take no more than 1 minute.
Momentum is just the quantity of motion for a moving object.
Hence you need mass and velocity.
→p=m→v
where→p is momentum,m is mass inkg , and→v is velocity inm/s .
So...
→p1=m1→v1
→p2=m2→v2
→p1 ? →p2
(5 kg)(8 m/s) ? (12 kg)(2 m/s)
40 kg⋅m/s>24 kg⋅m/s
Hence
→p1>→p2
