Answer:

See the explanation below,

Explanation:

Momentum is defined as the product of mass by Velocity. In this way, we will replace the following equation in each of the cases.

[tex]P=m*v[/tex]

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

A)

[tex]P = 10000*0\\P=0[/tex]

B)

[tex]P=100*5\\P=500[kg*m/s][/tex]

C)

[tex]P=1200*15\\P=18000[kg*m/s][/tex]

D)

[tex]P=15*1000\\P=15000[kg*m/s][/tex]

From higher to lower momentum

C,D,B,A
