if you are given the mass of an object in pounds
The idea is to use conservation of momentum. Calculate the total momentum before the collission, add it up, then calculate the combined velocity after the collision, based on the momentum.
conservation of momentum
According to the law of conservation of momentum which states that in a closed system momentum before collision is equal to the momentum after collision.
There is a Law of Conservation of Momentum, which states that total momentum is always conserved. In this case, that means that - assuming no additional bodies are involved - the total momentum before the collision will be the same as the total momentum after the collision. It doesn't even matter whether the collision is elastic or not.
the total momentum after a collision must be equal the total momentum before the collision.
The momentum before and after is the same, due to the Law of Conservation of momentum. Thus if you calculate the momentum before, then you have the after momentum or vice-versa.
because you get momentum and tou're moving faster.
Momentum.
The idea is to use conservation of momentum. Calculate the total momentum before the collission, add it up, then calculate the combined velocity after the collision, based on the momentum.
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.

The same as the total momentum before the collision.
That means that total momentum doesn't change. It is the same before and after the collision.
Momentum before = momentum after. Since there was no movement before, momentum before = 0 If you think of the bullet as forward/positive momentum and the gun as backward/negative momentum then the momentum of the bullet plus the momentum of the gun =0 and therefore the momentum of the bullet = the momentum if the gun. momentum = mass x velocity P=m/v 20gx150m/s = 2000g (2kg) x velocity 3000 = 2000v 3000 / 2000 = v v = 1.5m/s
