Imagine two billiard balls on a pool table. Ball A has a mass of 2 kilograms and ball B has a mass of 3 kilograms. The initial velocity of ball A is 9 meters per second to the right, and the initial velocity of the ball B is 6 meters per second to the left. The final velocity of ball A is 9 meters per second to the left, while the final velocity of ball B is 6 meters per second to the right. 1. Explain what happens to each ball after the collision. Why do you think this occurs? Which of Newton’s laws does this represent? 2. What can you say about the total momentum before and after the collision? 3. What do you think would happen to the velocity of each ball after the collision if the masses and initial velocities of each ball were the same? 4. The mass of ball A is 10 kilograms and the mass of ball B is 5 kilograms. If the initial velocity is set to 3 meters per second for each ball, what is the final velocity of ball B if the final velocity of ball A is 2 meters per second? Use the elastic collision equation to find the final velocity of ball B. Assume ball A initially moves from right to left and ball B moves in the opposite direction. Identify each mass, velocity, and unknown. Show your work, including units, and indicate the direction of ball B in your answer. 5. If the mass of each ball were the same, but the velocity of ball A were twice as much as ball B, what do you think would happen to the final velocity of each ball after the collision? To answer this question, create a hypothesis in the form of an if-then statement. The “if” is the independent variable, or the thing that is being changed. The “then” is the dependent variable, or what you will measure as the outcome. (Please show your work if you can)

in order to float. 145 metric tons= 145,000 kilograms. Use the rough-but-close rule
of thumb that 1 liter of water has 1 kilogram of mass. So the barge displaces 145,000
liters, which is also 145 cubic meters of water.
(Length) x (width) x (depth of the part under water) = 145 cubic meters
Draft of the barge (depth under water) = 145 / (50 x 20) = 145/70 = 2.07 meters.
No, it will not clear the reef 1.5 meters below the surface. Either the barge will shave off the top 0.57 meter of the reef, or else the reef will do serious damage to the barge. In any case, there will be a situation.

The acceleration is
Explanation:
We can answer this question by using Newton's second law, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem, we have
m = 25 kg is the mass of the rider+bicycle
F = 400 N is the force
Solving for a, we find the acceleration:

Answer:
Crest to the lowest point on the wave trough
Explanation:
The amplitude of the wave is the height of wave as measured from the highest point on the wave that is known as peak or crest to the lowest point on the wave known as trough. Wave length refers to the length of wave from one peak to another but amplitude or height can be determine by measuring the distance from its crest to its trough.
Final answer:
The amplitude of a wave is the maximum distance, or 'height', from the equilibrium position to the crest (highest point) or trough (lowest point) of the wave. This represents maximum displacement of the wave from its rest position.
Explanation:
The amplitude of a wave refers to the distance from the equilibrium or midpoint of the wave (the rest position) to the highest point of the wave known as the crest, or to the lowest point known as the trough. For instance, considering a wave on a graph representing a sound wave, the crest would be the highest peak on the graph and the trough would be the lowest point. We can visually represent this extent as height, but it's actually a measurement of maximum displacement of the wave from equilibrium (rest position). For physical waves, such as sound or light waves, a larger amplitude leads to a louder sound or a brighter light.
