Explanation / Answer

According to the given problem,

Answer:

a) Positive[minimal]

b) Zero[minimal]

c) Positive[maximum]

d) Positive [Maximum]

e) Zero [minimal]

Reason: At eqlibrium position[x=0] K.E is maximum and P.E is zero,at extream position [x =+/-A] P.E is maximum and K.E is negative as it is considered at rest.

And energies are always positive or zero, no negative energy is there in this mostion.
