Mark is conducting an experiment to show how an object’s kinetic energy is affected by its mass and velocity. First, he lets an empty wagon roll down a hill and calculates its kinetic energy. Next, he repeats the experiment after placing a bag of sand in the wagon.

The wagon will have more kinetic energy than when it was empty.
The best prediction for the second part of Mark's experiment is: "The wagon will have more kinetic energy than when it was empty."
To predict the outcome of the second part of Mark's experiment, we need to consider the factors that affect the kinetic energy of an object - mass and velocity.
In this case, Mark is adding a bag of sand to the wagon, which increases the mass of the wagon without changing its velocity. The formula for kinetic energy is KE = 0.5 * mass * velocity^2.
Since the mass of the wagon increases with the added bag of sand, and the velocity remains the same, the kinetic energy of the wagon will indeed be greater than when it was empty.
Therefore, the best prediction for the second part of Mark's experiment is: "The wagon will have more kinetic energy than when it was empty."
