- Consider 2 spheres weighing 1 kg each and traveling at 50 m/s toward a wall. The spheres have the same density and presented area but when they hit the wall, sphere A breaks apart and falls to the ground while sphere B falls to the ground but does not break apart. Do the spheres transfer the same amount of energy into the wall? If not, which sphere transfers more energy into the wall?
- KE=0.5 x mass x velocity^2
I assume KE is conserved therefore, the KE transferred will be the same. But intuitively, this doesn't seem correct. Seems like the object that breaks apart would transfer less energy than the object that doesn't. Any thoughts?
