The kinematics and conservation of momentum relationships allow to find the results for the questions about the measurements and conditions to know the accident conditions are:
1) The principles of conservation of momentum and kinematics.
2)
3) The factors that influence the direction and distance traveled are:
The initial speed of the vehicles
The mass of the vehicles
Pavement conditions: dry, wet, humid, with dirt or loose sand.
1) Kinematics studies the movement of bodies, they look for relationships between position, speed and acceleration.
To analyze the accident, you must answer a question such as what speed the vehicles had before the accident, this is the initial speed of each one and their directions.
When reviewing the kinematics relationships we have.
Where the acceleration is given by Newton's second law.
fr = m a
The friction force is given by the expression.
fr = μ N
fr = μ mg
Let's Substitute.
μ m g = m a
a = μ g
The friction coefficient is tabulated, for different types of rubber, pavement and wet, dry conditions, etc.
Therefore, the researcher must measure the braking distance of the vehicles, which can be taken from the mark of the tires on the road and note the condition of the pavement if it is dry or wet and the visibility of the day.
This is the speed of the vehicles just after the impact, using the law of conservation of momentum you can find the speed of the vehicles before the impact
\f
Where this is a vector expression, which in general is solved with the components of each directional.
Consequently to answer the questions you must use the principles of conservation of momentum and kinematics.
2) If the vehicles travel at right angles and their masses are similar, the direction after the collision in each direction.
3) The factors that influence the direction and distance traveled are:
The initial speed of the vehicles
The mass of the vehicles
Pavement conditions: dry, wet, humid, with dirt or loose sand.
In conclusion, using the kinematics and conservation of momentum relationships, we can find the answers to the question about measurements and conditions to know the accident conditions are:
1) The principles of conservation of momentum and kinematics.
2)
3) The factors that influence the direction and distance traveled are:
The initial speed of the vehicles
The mass of the vehicles
Pavement conditions: dry, wet, humid, with dirt or loose sand.

Answer:
Explanation:
This is the row echelon form of A. This means that only two of the vectors in our set are linearly independent. In other words, the first two vectors alone will span the same subspace of as all three vectors.
Therefore, the linearly independent spanning set for the subspace is
