The best way to start a physics problem is with a diagram. We have two objects moving ... and increasing in velocity and the car is moving horizontally with (I assume) a constant velocity.

The magnitude is usually modeled as: Rho is the density of the stuff the object is moving through A is ... the opposite direction as the velocity. Here is a diagram of a sky diver that just ...

This is the maximum velocity ... acting on the object are balanced and there is no resultant force. The object is stationary or at a constant speed. If an object is moving upwards and the forces ...

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity ... that the object and reference frame are moving relative ...
