That begs the question of which Zaku II you want to measure.

Well, let's take them in alphanumerical order and see.

The MS-06D Zaku II Desert Type has a base weight of 61.3tons, a full weight of
79.4 tons, an acceleration of 0.54 G, and a ground speed of 80 KPH.

The MS-06E Zaku II Reconnaisance Type has a base weight of 60.4 tons, a full
weight of 76.2 tons and an acceleration of 0.71 G. No ground speed is given.

The MS-06F Zaku II has a base weight of 58.1 tons, a full weight of 73.3 tons,
an acceleration of 0.59 G, and a ground speed of 88 KPH.

The MS-06FZ Modifed Zaku II has a base weight of 56.2 tons, a full weight of
74.5 tons and an acceleration of 1.07 G, and a ground speed of 103 KPH.

The MS-06F2 Zaku II Type F2 has a base weight of 49.9 tons, a full weight of
70.3 tons and an acceleration of 0.76 G. No ground speed is given.

The MS-06J Zaku II has a base weight of 56.2 tons, a full weight of 74.5 tons
and an acceleration of 0.69 G. No ground speed is given.

The MS-06J Zaku II Ground Unit has a base weight of 56.2 tons, a full weight of
70.3 tons, an acceleration of 0.65 G, and a ground speed of 85 KPH.

The MS-06K Zaku Cannon has a base weight of 59.1 tons, a full weight of 83.2
tons, an acceleration of 0.49 G, and a ground speed of 73 KPH.

The MS-06M (MSM-01) Zaku II Marine Type has a base weight of 43.3 tons, a full
weight of 60.8 tons, an acceleration of 1.09 G, and a water speed of 45 knots
(Nautical MPH).

The MS-06R-1A Zaku II High Mobility Type has a base weight of 61.8 tons, a full
weight of 76.8 tons and an acceleration of 0.68 G. No ground speed is given.

The MS-06R-2 Zaku II High Mobility Type has a base weight of 49.5 tons, a full
weight of 7.50 tons and an acceleration of 0.80 G. No ground speed is given.

The MS-06R-3 Zaku II High Mobility Type has a base weight of 43.5 tons, a full
weight of 74.5 tons and an acceleration of 0.77 G. No ground speed is given.

The MS-06RD-4 Zaku II Test Type has a base weight of 60.3 tons, a full weight of
77.5 tons and an acceleration of 0.69 G. No ground speed is given.

The MS-06S Zaku II Commander Type has a base weight of 56.5 tons, a full weight
of 75.2 tons and an acceleration of 0.69 G. No ground speed is given.

And, for what it's worth, the OMS-06RF RF Zaku II (Oldsmobile Army, circa UC
0120) has a base weight of 24.6 tons, a full weight of 45.8 tons and an
acceleration of 1.37 G. No ground speed is given.

Now, what we really need here is the thrust-to-weight or mass ratio. I can't
find one for the Zaku line, but the RMS-106 Hizack has a mass ratio of 1.33,
along with an acceleration of 1.09 G for a mass between 38.7 and 59.6 tons. The
RMS-106CS Hizack Custom pushes that to 1.22 G for a mass between 35.6 and 60.7
tons, but no mass ratio is given.

It's also worth noting that an acceleration of 1 G is equivalent to 9.80665 m/s2
or 35.3039 km/(h.s) and that terminal velocity in Earth's atmosphere is about
193.121 KPH.

I suspect that the Zaku uses a running jump, augmented by a jet-assisted
take-off (JATO) rocket or jump jet to get airborne and doesn't have much in the
way of "hang time" thereafter.

It's therefore my considered opinion that the Zaku II has an average air speed
of 90 to 100 KPH across a span of about 100 meters.
