A block on a rough, horizontal surface is attached to a horizontal spring of negligible mass. The other end of the spring is attached to a wall. The spring is
compressed such that the block is located at position X. When the block-spring system is released, the block travels to the right through position Y and
continues to travel to the right through position Z. Free body diagrams for the block at positions X, Y, and Z are shown in the figure. At which position does the
block have the greatest kinetic energy?
A
Ñ…
B
Y
Z
The answer cannot be determined without knowing the exact speed of the block at each position.
