a 25 kg child is initially riding in a 50 kg cart moving at a speed of 2.0 m/s. the child manages to jump off the back of the cart in such a way that he has no final velocity. what is the resulting velocity of the cart? compare the child's change in momentum to the cart's change in momentum. what additional information would be needed in order to determine the force the child used to jump off the cart?​

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
