A 120 N/m spring is compressed 0.25m and is used to launch a 0.5kg ball. What is the momentum of the ball immediately after it is fired?

Momentum of the ball just after the release is 1.94 kg m/s

Explanation:

As we know that initially the spring and compressed against the ball

So here we will have

now we have

Here we know that

mass = 0.5 kg

k = 120 N/m

x = 0.25 m

now we can use formula of momentum here

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
