25e--Mhead = 9

For m_head = 9 lb
Increasing the mass of the head to 9 lb shifts the pattern of constraints far enough to the left to begin to exclude some of the acceptable values. This decreases the number of allowable values from 30 to 20. Again the constraints imposed by v_frags > 1100 ft s^-1 coincide closely with those for PE < 0, but are less restrictive by three cases. The more restrictive PE mask is shown in all tables.

The allowed values of PE range from 140 to 600 ft-lb, very similar to the previous ranges. The mask here is based on both PE and v_frags.

The allowed values for v_frags ranged from 420 to 900 ft s^-1, very similar to previous ranges. The mask shown below represents v_frags and PE.

With the leftward movement relative to m_head = 8 lb, the disallowed area at the upper right continued to increase, but still fell within the broader area of values disallowed by PE.

The speed of the lurch ranged from -16.6 to +4.6 ft s^-1. The acceptable speeds, all rearward, were 0.9–1.2 ft s^-1, very similar to the previous ranges.
