I think it is the wave energy.
Wave energy also known as the ocean energy is the energy harnessed from the ocean or sea waves. It is a source of power that comes from the endless march of the waves as they roll into the shore then back out. Using wave energy is advantageous as they are environmental friendly as there are no harmful byproducts, and also the energy from waves can be taken directly into electricity-producing machinery and used to power generators.
a) 14.4 m/s
The problem can be solved by using the law of conservation of total momentum; in fact, the total initial momentum must be equal to the final total momentum:
So we have:
(1)
where
is the mass of each ball
is the initial velocity of the green ball
is the initial velocity of the blue ball
is the final velocity of the green ball
is the final velocity of the blue ball
Simplifying the mass in the equation and solving for , we find
b) 12.0 m/s
This time, the green ball continues moving after the collision at
So the equation (1) becomes
And solving for we find
c) 13.5 m/s
This time, the green ball continues moving after the collision at
So the equation (1) becomes
And solving for we find
They are doing the transform type of tectonic plate movement. This is a process where the plates move sideways. But they move at a rate of a few inches a year. Did that help you?
