Car 1 and Car 2 have equal masses of 2,000 kg each. Car 1's initial momentum was 40,000 kg-m/s to the right; Car 2 wasn't moving.
Car 1 collided with Car 2.
Car 1's final velocity is 10 m/s to the right; Car 2's final velocity is unknown.
1. What is each car's initial velocity?
2. What is their total initial momentum?
3. After the collision, what is Car 2's final velocity?
4. What is their total final momentum?

Please dont answer unless you can help

work it out

Explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
