Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
The event is most likely to happen when K melts. So, option (c) or (iii) is the correct answer.
<h3>Why does it melt in point K?</h3>
Melting refers to the transformation of a solid into a liquid when heat is applied. Melting occurs when solid rock in crystalline form is exposed to severe heat, pressure, or both, causing it to change phase into a liquid known as magma.
