A meteor whose mass was about 1.5 x 10^8 kg struck the Earth (m= 6.0 x 10^24 kg) with a speed of about 25 km/s and came to rest in the Earth. a) What was the Earth's recoil speed (relative to Earth at rest before the collision)? b) What fraction of the meteor's kinetic energy was transformed to kinetic energy of the Earth?

Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect. This leads to gradual increase of raw mill SEC. Filling level of grinding balls is also important in grinding efficiency. Optimum level of filling should be maintained.

Exceptional grinding performance and energy savings are the result of the VIBRA-DRUM® unit's natural frequency design. A sub-resonant, two mass drive and spring system alternately stores and releases grinding power. Once in motion, energy is only needed to move the grinding media as a fluid mass, and to overcome frictional losses.
