Question

Tsunami waves generally carry a mass (m) of 770 kg of water, travel at a velocity (v) of approximately 10 m/s and have a height (h) of 10 m at landfall. The colony structures can withstand a total energy (TE) 135,000 J before catastrophic damage occurs.Calculate the potential energy (PE) of a tsunami wave based on the provided date. (Note: g = 9.8 m/s2) PE = m•g•h

Answer 1

Given:

The mass is m = 770 kg

The height is h = 10 m.

Also, the acceleration due to gravity is g = 9.8 m/s^2.

To find the potential energy.

Explanation:

The potential energy can be calculated as

$\begin{gathered} P\mathrm{}E\text{. =mgh} \\ =770\times9.8\times10 \\ =75460\text{ J} \end{gathered}$

Final Answer: The potential energy of Tsunami waves is 75460 J.
