### Ball Milling

For example, oxide-dispersion-strengthened alloys are synthesized using a powerful high-energy ball mill (attritor) because conventional ball mills could not provide sufficient grinding energy  Intensive research in the synthesis of new metastable materials by HEBM was stimulated by the pioneering work in the amorphization of the Ni-Nb alloys conducted by Kock et al in [ 39 ].

### What is KE of a projectile at its maximum height?

It depends upon whether the projectile is vertically upwards or at an angle with horizontal 1: If body is moving vertically upward then it would definitely be zero at the top most point since there is only vertical velocity applied to the body (i.

### How to find the maximum height of a ball when given

The key in these problems is “maximum height” This means that the final velocity (velocity at the maximum height) is 0 It will always be 0 in these cases since the ball has to stop before changing direction Also, even if you are not given it, y.
