Answer:
A. Mantle
Explanation:
Mantle is the process that drives plate tetonics, thus being that layer of the Earth.
The answer would be:
6,250 joules
Here's how to do it:

KE = kinetic energy (joules)
m = mass (kg)
v = velocity (m/s)
So with that formula let's figure out what was given to you.
500 kg and 5m/s
You know which is which based on the unit.
m = 500kg
v = 5m/s
Now all you need to do is plug it into your formula and solve.





The unit
also means joules
So the final answer is 6,250 joules.
Answer:
B
Explanation:
