I can't believe I'm gonna waste brainpower on this but here goes:
If Grasshopper sends someone 10m straight up before coming to a complete stop

using v_f^2 = v_0^2 - 2*g*(y-y_0)
where y = 10m, y_0 = 0m, v_f = 0 m/s, g = 9.8 m/s^2

0 = v_0^2 - (19.6 m/s^2)*(10m - 0m)
v_0 = 14m/s

If you launched someone exactly sideways with that initial velocity to make 60m they would have to be about 90m off the ground to make that distance, or about 25 stories up.

dam we still doin black box arguments huh
