Problem

Four stones A, B, C and D are thrown horizontally from the same height with the following speeds: A: 4 m/s4\,\text{m/s} (mass 0.3 kg0.3\,\text{kg}) B: 6 m/s6\,\text{m/s} (mass 0.2 kg0.2\,\text{kg}) C: 3 m/s3\,\text{m/s} (mass 0.4 kg0.4\,\text{kg}) D: 5 m/s5\,\text{m/s} (mass 0.3 kg0.3\,\text{kg}) (i) List the stones in descending order of kinetic energy, indicating any ties. (ii) Write one sentence to justify the position of stone C in your list.
