An apple is suspended a string and a spring in parallel. When the string is cut, the apple falls, and the spring stretches and contracts repeatedly as the apple bounces. Describe the energy conversions that occur during this process.
When the string is cut:Gravitational potential energy is converted to kinetic energy.Kinetic energy is converted to elastic potential energy.Elastic potential energy is converted to kinetic energy (and heat energy)Kinetic energy is converted to gravitational energy.Repeat steps 1 to 4 until stationary.
