Cracking the SAT Physics Subject Test

(Marvins-Underground-K-12) #1

  1. 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.

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

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