a child sees an empty soda can resting on the icy surface of a frozen pond and throws a stone at it the stone hits the can which then slides across the ice decreasing in speed as it does so at the edge of the pond the can hits a pile of snow and stops
which of the following would be the appropriate energy giver in such an explanation
a.the child
b.the stone
c.the soda can
d.the ice
e. the pile snow
didn't the child throw the stone?

The appropriate energy giver in this scenario would be (b) the stone.
To understand why, let's break down what happens in the situation:
1. The child throws a stone at the empty soda can. By applying force to the stone, the child gives it kinetic energy.
2. The stone hits the can, transferring its kinetic energy to the can. This sudden transfer of energy causes the can to start moving across the ice.
3. As the can slides across the icy surface, it encounters friction between the can and the ice. This friction opposes the can's motion, causing it to gradually decrease in speed.
4. Finally, when the can reaches the edge of the pond, it hits a pile of snow. The impact with the snowpile transfers the remaining kinetic energy of the can to the snow, causing it to come to a stop.
Therefore, the stone is the energy giver in this scenario, as it is what initiates the movement of the can and transfers its kinetic energy to the can.
