Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground. Ball 3 is faster than 1 is faster than 2. Ball 2 is faster than 1 is faster than 3. Ball 1 is faster than 2 is faster than 3. Ball 3 is faster than 2 is faster than 1.
All balls have the same speed on impact.
Two highly-elastic superballs, the first much larger than the second, are dropped in rapid succession from a point one meter high.
