The 20-kg object has the greatest momentum.

Explanation:

The equation for momentum is #p=mv#, where #p# is momentum, #m# is mass in kg, and #v# is velocity in m/s.

Momentum for 5 kg, 4 m/s object.

#p="5 kg"xx"4 m/s"=20"kg"*"m/s"#

Momentum for 20 Kg, 20 m/s object.

#p="20 kg"xx"20 m/s"="400 kg"*"m/s"#
