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 0.014 J 0.014 J 0.0035 J 0.0035 J 0.00175 J 0.00175 J 0.007 J
Since the kinetic energy is directly proportional to the mass, the best prediction for the kinetic energy of the second marble would be half of the first marble's kinetic energy. Therefore, the best prediction for its kinetic energy at the end of the plane would be 0.00175 J.
