Answer:
-2, -4, -6, -8, -10......
Step-by-step explanation:
The sequence is in a decreasing order of -2 for the next sequence.
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
