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
