Описание слайда:
Concept Question Answer According to Newton’s Third Law, the two forces are equal and opposite. Because of the huge difference in masses, however the space shuttle accelerates much more towards the Earth than the Earth accelerates toward the space shuttle. a = F/m

Описание слайда:
How to solve Problem 2 A force of 200 N accelerate a bike and rider at 2m/s^2. What is the mass of the bike and rider? F = ma therefore:m =F/a m = 200N/2m/s^2 N= kgm/s^2 so when divide your answer will be kg left. m = 100kg
