Answer:
v ≈ 4.47
Explanation:
The Formula needed = <u>KE = </u>
<u> m v²</u>
<u></u>
Substitute with numbers known:
2000J = × 200kg × v²
Simplify:
÷100 ÷100 (Divide by 100 on both sides)
2000J = 100 × v²
= v²
20 = v²
√ √ (Square root on both sides)
√20 = √v²
4.472135955 = v (Round to whatever the question asks)
v ≈ 4.47 (I rounded to 2 decimal places or 3 significant figures, as that is what it usually is)
It would be D) the rope is pulled to the right. This is because their is a greater force in that direction.

If the earthquake is on land it would cause total devastation, building will fall ( depending on hos strong it was), people could die but land earthquake is generally more safer than if there was a earthquake underwater. if that happened there would be tsunamis along the coast and everything in its path would be destroyed and your belongings and stuff like cars could be in another town. hope this helps :)
