Cracking the SAT Physics Subject Test

Since the amplitude of the motion is 2.0 cm, the spring is stretched a
maximum of 5 cm + 2.0 cm = 7 cm when the block is at the lowest position in
its cycle, and a minimum of 5 cm − 2.0 cm = 3 cm when the block is at its
highest position.

The block’s speed is 0 at the two ends of its oscillation region, which
are the points described in question 11.

The block’s acceleration is 0 at its equilibrium position, which is the
point described in question 10.
