uuh, well, the guy that answers the questions with the link is a scammer and DO NOT click the link! it'll ask u to download stuff to ur computer/phone that you have no idea what it is-then u'll have to go and manually uninstall the things it made you download, which is such a pain. the guy also goes by many accounts that start with a b and has no profile pic, and if they answer the question, their answer is immediatly deleted but takes like a day for someone else to answer the question b/c it takes forever to process for that person's account/answer to be deleted-id k why- it just does

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.
