A block rests on a horizontal, frictionless table. It is attached to a spring and set into motion. The picture above shows snapshots of the block at 5 different labelled locations during the motion. The two extreme locations (Points B and C) represent the two extremes of the motion of the block. Point E represents the equilibrium position. Evaluate each statement below with the following:
PositiveZeroNegative
1. The kinetic energy of the block at location B is ____.
2. The kinetic energy of the block at location E is ____.
3. The potential energy of the spring at location D is ____.
4. The kinetic energy of the block at location D is ____.
5. The potential energy of the spring at location E is ____.
