mark is conducting an experiment to show how a objects kinetic energy is affected by its mass and velocity first he lets an empty wagon roll down a hill calculates its kinetic energy next he repeats the experiment after placing a bag of sand in the wagon which best prediction for the second part of his experiment?
1 answer
The best prediction for the second part of Mark's experiment is that the kinetic energy of the wagon with the bag of sand will be greater compared to the empty wagon. This is because the presence of the bag of sand increases the mass of the wagon, and according to the formula for kinetic energy (KE = 1/2mv^2), increasing the mass while keeping the velocity constant will result in a higher kinetic energy.
