Homework Statement
The original superman leaps into the air to land on an 85.5 m high building. What was his intial velocity?
d = 85.5 m
v2 = 0
v1 = ?
a = 9.8 m/s2 (I'm not sure about this one so I just used acceleration due to gravity)
Homework Equations
v2 = v1 + 2ad (?)
The Attempt at a Solution
I'm really not sure what acceleration value to use for this or if I can solve it without using acceleration
