Question

Anwser only please:
Newton approximated motion in a circle as a series of linear motions, as in the polygon below.

Answer 1

Answer only? I don't think so. Thinking is required. What's the acceleration necessary to change a velocity vector from to

Answer 2

Ah, so it would be answer 4?

Answer 3

Wait, 2, it would be 2 because the abel is opposite to vel, correct?

Answer 4

What vector do you need to add to the first velocity vector to get the second velocity vector? That vector that you add--that's the acceleration. It's not #2.

Answer 5

Hence the answer is #3.

Answer 6

Make sense?
