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 order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
