Since kinetic energy is directly proportional to mass, and the second marble has half the mass of the first marble, we can predict that its kinetic energy at the end of the plane will also be half that of the first marble.
So, the best prediction for its kinetic energy at the end of the plane would be 0.00175 J.
A student rolls two marbles down an inclined plane. One marble has a mass of 4.8 grams. The student calculates its kinetic energy to be 0.0035 Joules when it reaches the end of the plane. The second marble has a mass of 2.4 grams. What is the best prediction for its kinetic energy at the end of the plane?(1 point) Responses 0.0035 J 0.0035 J 0.007 J 0.007 J 0.014 J 0.014 J 0.00175 J
