During World War II, there was a practice that people would remove some of the gold coins but not enough to not be recognized as a US gold coin. A 1933 Double Eagle gold $20 piece had a mass of 30.0926 grams brand new. If 1.0000 grams was removed, and the United States minted 445,500 coins in 1933, how much money did the government lose by this practice assuming all 445,500 coins were modified. The price of gold today is $1798.53 per oz.

your picture is not part of the scientific method.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

diaria maybe go see a doctor about that
