At 11:06 you can see that zombie went up and over a ~10 m tree in ~3 seconds.

a=Voy^2/(2*h)

t/2=v/a

So, 8*h/t^2=a

Thus,

8*10/(3^2) = a = 8.9 m/s^2 ~ equal to EARTH (Especially if you consider drag)

In fact, to get the moons gravity of 1.624 m/s^2 the tree would need to be,

8*h/(3^2) = 1.624 => h = 1.827 meters tall, which is likely SHORTER than out hero."

Im confused where he got his equations, because it doesnt seem valid taht you can calculate acceleration, which is change in velocity, with only the change in distance over time.
