ENERGY AND MOMENTUM: Which Object Will Roll Down a Hill More Rapidly?

If a buggy and a sphere of equal masses begin rolling side-by-side down a hill, which will reach the bottom of the hill first ( neglecting wind resistance ) ? For simplicity, we should pretend that the energy transfer in this problem is 100% efficient: no losses occur due to sound, random vibrations, or windContinue reading “ENERGY AND MOMENTUM: Which Object Will Roll Down a Hill More Rapidly?”
