Using kinematic reasoning, the answers for the changes that can cause crashes are:
we can manipulate
- The speed of the vehicles, especially that of the second car
- he traffic light change time
- Change some condition of the pavement after the first vehicle passes
Autonomous systems are systems that take a series of signals from the outside, analyze them and carry out actions according to how to handle them.
In that case you have two cars one behind the other at a short distance a traffic light with a yellow light is approaching.
Some parameters can be modified to cause the crash:
- The car in front accelerates to pass the traffic light, but the traffic light changed to red, in this case if the car behind also accelerated, there may not be enough distance to stop and crash.
- You can change the traffic light to green whereby the first car continues its speed, but the traffic light time changes very quickly to red, whereby the first car stops, but the car behind cannot stop.
- The car behind accelerates to also pass the yellow light, but turns red and the first one crashes to a stop.
- We change some condition of the pavement after the first vehicle passes, for example wetting the pavement, which decreases the coefficient of friction, consequently the second vehicle does not have time to stop.
We can appreciate that if there is not a good and fast communication between the two vehicles, it is easy for them to crash.
In conclusion, using kinematic reasoning, the answers for the changes that can test shocks are found:
- The second vehicle increases speed and the first must brake sharply

Answer:
Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end. These supports, called the abutments, carry the load and keep the ends of the bridge from spreading out.

Answer:
Explanation:
This is a simple Law of Momentum Conservation problem of the inelastic type. The equation for this is
![[m_1v_1+m_2v_2]_b=[(m_1+m_2)v]_a](https://tex.z-dn.net/?f=%5Bm_1v_1%2Bm_2v_2%5D_b%3D%5B%28m_1%2Bm_2%29v%5D_a)
Filling in:
![[1200(4.5)+2100(0)]=[(1200+2100)v]](https://tex.z-dn.net/?f=%5B1200%284.5%29%2B2100%280%29%5D%3D%5B%281200%2B2100%29v%5D)
which simplifies to
5400 + 0 = 3300v
so v = 1.6 m/s to the east, choice B
Answer:
all the forces occur in pairs that if one object exerts a force on another object, then the second object exerts an equal and opposite reaction force on the first.
Answer:
Acceleration is the rate of change of velocity with time.Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. Average acceleration is determined over a "long" time interval.
