Yes, in the context of driving, when applying the 3-Second Rule, you should choose a fixed or stationary object on the road ahead. This helps you maintain a safe following distance from the vehicle in front of you by ensuring that you have at least a 3-second gap between your vehicle and the one in front.
A stationary object is not a good reference point when applying the two-second rule because it may move unexpectedly or not provide a consistent speed reference. It is better to use a fixed reference point on the road ahead, like a sign or a pole, to ensure a safe following distance.
A soft drink can is not a good object to use when applying the two-second rule while driving. It is best to focus on the vehicle directly ahead of you and ensure that there is a two-second gap between your vehicle and theirs to maintain a safe following distance.
A good object to use when applying the two-second rule while driving is a fixed point on the road, such as a sign or a tree. Start counting when the vehicle ahead of you passes the object, and ensure that you pass it no sooner than two seconds later to maintain a safe following distance.
A soft drink can would not be a good object to use when applying the two-second rule, as it is too light and might be easily blown away by wind or affected by external factors, leading to an inaccurate measurement of the following distance between vehicles. It's best to use a more stable and solid object for a more reliable estimation.

-- Take two snapshots of it, at two different times. -- If it's in different places in the two photos, it's definitely not stationary. -- If it's in the same place in both photos, then it may or may not be stationary. It could be returning periodically to the same place, and you just happened to catch it on two occasions when it was in the same place. So if the photos are identical, you must ... -- Take two more snapshots, at two different times, spaced by a different length of time from the first pair of photos. -- If the object's position is the same in both of the second set of photos, then it's truly stationary.
The first one sets the system of coordinates (inertial). The second one gives connection between the net force and the acceleration. The third one postulates than if a first object applies some force F to a second object. The second object is applying the same force F to the first object.
This scenario violates the law of conservation of momentum. If the two objects collided perfectly elastically, the first object would transfer its momentum to the second object, causing both objects to move with a final velocity determined by momentum conservation equations.
You can make an object accelerate by applying a force to it in the direction you want it to move. According to Newton's second law of motion, the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.
To find the acceleration of an object connected by a string, you can use Newton's second law: ΣF = ma, where ΣF is the net force acting on the object. To find tension in a string, consider applying Newton's second law separately to each object connected by the string and analyzing the forces acting on each object.
