Answer:
Explanation:
Using the law of conservation of momentum;
here;
There is a need for conservation of the total momentum that occurred before and after the collision.
So;
= mass of cart X
= mas 9f cart Y
= velocity of cart X (before collision)
= velocity of cart Y (before collision)
= velocity of cart X (after collision)
= velocity of cart Y (after collision)
So;
because the mass is identical and v represents the velocity of both carts.
Now;
= 2 m/s
= 0 ( at rest)
∴
m(2) = (2m)v
v = 1 m/s
Thus, we can see from the graphical image attached below that the velocity of X reduces to 1 m/s after collision with cart Y.
The reason for that is that P-waves (primary waves) travel faster than S-waves (secondary waves).
If we call
the speed of the primary waves and
the speed of the secondary waves, and we call
the distance of the seismogram from the epicenter, we can write the time the two waves take to reach the seismogram as
So the lag time between the arrival of the P-waves and of the S-waves is
We see that this lag time is proportional to the distance S, therefore the larger the distance, the greater the lag time.
Uh.. what's the question..?
