Brief review of Newtonian formalism 1 Newton`s Laws of Motion 2
... Newtonian mechanics becomes complicated to use for systems with constraints, especially if the system considered contains several interacting objects. The prescription is to write the second law [Eq. (1)] for each body in the system. Thus, for a total of N bodies, there is a total of 3N secondorder ...

... A racing car is moving around the circular track of radius 300 meters shown above. At the instant when the car's velocity is directed due east, its acceleration is directed due south and has a magnitude of 3 meters per second squared. When viewed from above, the car is moving (A) clockwise at 30 m/ ...
