Questions: LEARN MORE REMARKS Because the impact is inelastic, it would be incorrect to equate the initial kinetic energy of the incoming bullet to the final gravitational potential energy associated with the bullet-block combination. The energy isn't conserved! QUESTION The ways that mechanical energy is lost from the system in this experiment include: (Select all that apply.) energy loss from the change in height of the block friction to bring the bullet to a stop relative to the ground thermal energy loss due to air drag emission of sound waves friction in the mechanisms

Solution Steps

The question pertains to an inelastic collision where a bullet impacts a block, and the system loses mechanical energy. We need to identify the ways in which this energy is lost.

• Energy loss from the change in height of the block: This is not a loss mechanism but a conversion of kinetic energy to potential energy.
• Friction to bring the bullet to a stop relative to the ground: This is a valid mechanism as friction converts kinetic energy into thermal energy.
• Thermal energy loss due to air drag: Air drag converts kinetic energy into thermal energy, which is a valid loss mechanism.
• Emission of sound waves: Sound waves carry energy away from the system, making this a valid loss mechanism.
• Friction in the mechanisms: Friction in any mechanical parts of the system converts mechanical energy into thermal energy, making this a valid loss mechanism.
