Final answer:
To find the potential energy of the egg after 0.6 seconds, subtract the kinetic energy (0.8 J) from the total mechanical energy (3.5 J), resulting in a potential energy of 2.7 J.
Step-by-step explanation:
The question is about calculating the potential energy of a falling egg when its kinetic energy and mechanical energy are known. Given the kinetic energy (KE) of the egg is 0.8 J and the total mechanical energy is 3.5 J, we can use the relationship that mechanical energy is the sum of potential energy (PE) and kinetic energy (KE), which is expressed as ME = KE + PE. To find the potential energy, we rearrange the equation to PE = ME - KE.
Substituting the given values:
PE = ME - KE
PE = 3.5 J - 0.8 J
PE = 2.7 J
Therefore, the potential energy of the egg after 0.6 seconds is 2.7 J.
