Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 46 meters
1 answer:
Answer:
The wavelength of the water is
Explanation:
From the question awe are told that
The distance between the two boats are 46 m
Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as
Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)
= 4.5
Now the wavelength of the water is

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.
