A block on a horizontal surface is attached to a spring fixed to a wall. A student pulls the block away from its rest position, stretching the spring, and releases it. The block oscillates horizontally and eventually comes to rest.
Which row in the table correctly identifies the type of energy transferred to the apparatus during the initial stretch, and the type of energy to which this has then been transferred when the block comes to rest?
| Type of energy transferred to the apparatus | Type of energy to which this has then been transferred when the block comes to rest | |
|---|---|---|
| A | elastic energy in the spring | chemical energy in the spring, surface, and air |
| B | elastic energy in the spring | thermal energy in the spring, surface, and air |
| C | kinetic energy in the block | chemical energy in the spring, surface, and air |
| D | kinetic energy in the block | thermal energy in the spring, surface, and air |
elastic energy in the spring | chemical energy in the spring, surface, and air
elastic energy in the spring | thermal energy in the spring, surface, and air
kinetic energy in the block | chemical energy in the spring, surface, and air
kinetic energy in the block | thermal energy in the spring, surface, and air
