6 m/s
This type of collision is a <u>Inelastic collision </u>
Explanation:
We begin by finding the momentum of the initial train car;
Remember that momentum is given by the formulae mass (kg) * velocity (m/s)
Therefore;
Momentum = 6000 * 10
= 60,000 kg⋅m/s
The other car has zero momentum because;
4000 * 0
= 0
When the two train cars collide, the total momentum will be;
60,000 + 0 = 60,000
Therefore to find the velocity, well use the same formulae;
p = mv whereby;
p – momentum
m – mass
v – velocity
60,000 = (6000 + 4000) * v
v = 60,000 / 10,000
v = 6
= 6 m/s
This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

Taiga is a winter type forest. Taiga is different then other ecosystems because other ecosystems are not has cold has Taiga. Taiga ecosystems can get has low has -70 °F (or -60° C)
But Taiga ecosystems can get has hot has 104°F (or 40°C)
Taiga ecosystems can get colder then tundra (which is another very cold too)
Some things that make the Taiga ecosystems unique is:
- Evergreen trees, the Taiga is COVERED with these.

IT IS NOT POSSIBLE to produce malleable cast iron in pieces having large cross sectional dimension. This is because, iron has a very rapid cooling rate and it will not be possible to achieve this rate at different cross sectional areas in a sheet of iron.
