Help me please
It is suggested that the tsunami was caused by an undersea landslide of 200 to 300 cubic kilometres, which slipped approximately 40 km down the continental slope. The continental slope in that area is approximately 4.3°. We can calculate the vertical movement (H)of the landslide to be about 3000 metres. The mass of the landslide, assuming a density of 2.67 gm/cm3 would be M = 483,381,084,627,827 kg.
The potential energy may be calculated using the equation:
E = 9.8*M*H
What is the potential energy released by the landslide? Again, your answer should be in joules.
Explanation / Answer
potential eenrgy U = mgh = 483,381,084,627,827 * 9.81 * 3000
U = 14225905320596948610 Joules
potential energy released by the landslide = vertical height * 9.81 * mass
PE = (40000* sin 4.3 * 9.81 * 483,381,084,627,827)
PE = 1.422187025187 *10^19 J
