A block is attached to an ideal horizontal spring.
• Experiment 1: The spring is compressed a distance x and released from rest.
• Experiment 2: The spring is compressed a distance 2x and released from rest.
Neglect friction.
Which statement correctly compares the block’s maximum speeds v1 (Experiment 1) and v2 (Experiment 2)?
a) v2=2v1
b) v2=v1
c) v2=2v1
d) v2=4v1
