The question seems to be incomplete. However, I can think of a possible logical question this problem could have. The equation for the maximum height attained by any object thrown upwards is:

H = v²/2g

I think the question would be determining the gravity in Io assuming that the initial velocity of the lava is the same. Then, the solution is as follows:

Let's use the other volcano to find v.

1.89*10⁵ m = v²/2 (1.72 m/s²)

Solving for v,

v = 806.325 m/s

So, we use this to find g in Io.

2*10⁵ m = (806.325) ²/2 (g)

Solving for g,

g = 1.6254 m/s²
