3. b? Hmmmm. acceleration= force/mass, and that is equal to kx/mass

so acceration depends on x

5. Hmmmm. At the extreme positions, velocity is zero, it changes directions, the question asked which is not true. Are you guessing or thinking?

7. WEll, you missed it three out of three, and your first guess was right. The velocity is NOT zero at the equilbrium position, it is maximum there.
