Explanation:
The following data is obtained from water property tables:
Part a)
The total mechanical energy of the skydiver is 178,000 J.
The given parameters;
- <em>Kinetic Energy of the skydiver, K.E = 100,000 Joule</em>
- <em>Gravitational Potential Energy of the skydiver, P.E = 78,000 Joules.</em>
<em />
The total mechanical energy of the skydiver is the sum of the kinetic energy and the potential energy.
<em>Total mechanical energy = K.E + P.E</em>
Total mechanical energy = 100,000 J + 78,000 J
Total mechanical energy = 178,000 J
Thus, the total mechanical energy of the skydiver is 178,000 J.
