... Assuming they stick, the only interesting force is F0 = 100 N and the total mass is mtotal = 50 kg. a = F0 /mtot = (100 N)/(50 kg) = 2.00 m/s2 . Continuing the stick-toghether assumption, focus on the the slab. The only force of interest is fs which accelerates it. fs = ms a = (40 kg)(2 m/s2 ) = 80 ...

The Third Law:
... The key to walking is the third law. You push against the ground and the ground pushes you. All there is to it. But how does that make you move? Okay, you takes your basic second law. It goes like this; you exert a force on the ground and it exerts a force on you. The two forces are equal and opposi ...

The Acceleration Due to Gravity
... The greater the force on an object, the larger is its acceleration. Probably the most apparent (and the weakest!) of all forces in nature is the gravitational force. Newton's Universal Law of Gravitation describes the mutual attractive gravitational force (Fg) exerted on each other by two objects wi ...
