Step 1

The formula for kinetic energy is given by: \[ KE = \frac{1}{2} m v^2 \] where $ m $ is the mass of the bullet and $ v $ is the velocity of the bullet. Show more…

Key Concepts

Kinetic Energy

Kinetic energy is the energy an object possesses due to its motion, calculated by the expression ½mv². This concept is used to determine how much energy the bullet had before it came to a stop in the ice.

Conservation of Energy

The conservation of energy principle states that energy cannot be created or destroyed, only converted from one form to another. In this situation, the bullet's kinetic energy is transformed into thermal energy that melts the ice.

Latent Heat of Fusion

Latent heat of fusion is the amount of energy required to change a substance from a solid to a liquid at its melting point without changing its temperature. This property is crucial for calculating how much ice is melted when it absorbs the thermal energy converted from the bullet's kinetic energy.
