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.

#vecp = mvecv#

where#vecp# is momentum,#m# is mass in#"kg"# , and#vecv# is velocity in#"m/s"# .

So...

#vecp_1 = m_1vecv_1#

#vecp_2 = m_2vecv_2#

#vecp_1" ? "vecp_2#

#("5 kg")("8 m/s")" ? "("12 kg")("2 m/s")#

#"40 kg"cdot"m/s" > "24 kg"cdot"m/s"#

Hence

#color(blue)(vecp_1 > vecp_2)#
