Answer 1

A. The position at the moment the mass is released should be represented by the plot at the far left on each graph. The mass has been pulled down -- the negative direction. Only graphs D and H are at a negative position at the far left, which is when t=0. Graph D does not show that the position changes as time increases while H does show is bouncing through the equilibrium position and up into positive territory, then back down, then repeating as time advances. It' H.

B. It is E because it starts at 0 and shots off, with velocity increasing, then stops then goes the other direction, with velocity going negative.

C. It is F. Because acceleration is the 1st derivative of the velocity, that's true.
