4. Each croquet ball in a set has a mass of 0.50 kg. The green ball, traveling at 12.0 m/s, strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless
surface and all collisions are head-on, find the final speed of the blue ball in each of the
following situations:
a. the green ball stops moving after is strikes the blue ball. (12 m/s)
b. the green ball continues moving after the collision at 2.4 m/s in the same
direction. (9.6 m/s)
c. the green ball continues moving after the collision at 0.30 m/s in the same
direction. (11.7 m/s)

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

technology is the application of the knowledge gained by science.
