A child in a wagon of total mass 32 kg is traveling at 1 m/s at the top of a large hill. The child-wagon system coasts down the hill. At the bottom of the hill they are traveling at 11 m/s.

d) Where do you think this change in momentum came from?

The change in momentum in the child-wagon system as it travels down the hill from 1 m/s to 11 m/s is due to the conversion of gravitational potential energy into kinetic energy.

As the child-wagon system moves downhill, it gains kinetic energy while losing potential energy. This change in energy is responsible for the change in momentum.

At the top of the hill, the system has gravitational potential energy due to its elevation. As it moves downhill, this potential energy is converted into kinetic energy, increasing speed. This increase in kinetic energy corresponds to an increase in momentum.

In this case, the change in momentum is a result of the energy transformation from potential energy to kinetic energy as the child-wagon system descends the hill.
