This states that if an object A exerts a force on
an object B, object B will exert the same magnitude of force on A, but in the opposite direction.

So my question is; if a box is stationary and I want to push it, according to the 3rd law, the box will push back with an equal but opposite force. So if the forces cancel out, how do I get the box moving, because 1 force has to be greater than the other for there to be a non-zero resultant force.

Where have I gone wrong in this thinking?

Thanks

A typical cheap quartz watch gains or loses 1 second per day. That being the case, if I take a quartz watch from a batch of many, then at least one of them will be 100% bang-on accurate - the sort of accuracy aficionados will pay a fortune for. Is this possible and what are the chances?

During a Chicago storm, winds can whip horizontally at speeds of 100 km/h. if the air strikes a person at the rate of 40 kg/s per square meter and is brought to rest, estimate the force of the wind on a person. assume the person a 1.50 m high and .50 m wide. compare to the typical maximum force of friction ( mu=1.0) between the person and the ground, if the person has a mass of 70kg.
