A 100 kg man is stuck, motionless, in the middle of a frozen pond. Imagine that the surface of the pond is frictionless. Because it's cold, he's wearing a coat. He wants to get off the pond. Since he has studied Newton's 3rd Law of Motion, and he knows about the conservation of momentum, he decides to throw his 2 kg coat away from him which will make him move as a reaction.

If he throws the coat at 25 m/s South from him, what will his velocity be as a result?

P (ball) is (Mass(ball) x Velocity(ball)) = P(man) is (Mass(man) x Velocity(man))

V = P / M ( + direction)

Group of answer choices

0 m/s

25 m/s South

0.5 m/s North

2 m/s North

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
