What takeoff speed would Superman need to leap tall buildings in a single bound?

Let the building be 200 metres tall or about 660 feet. The minimum speed would be:

v = sqrt(2gh)

v = sqrt(2*9.8*200)

v = 63 m/s

v = 140 mphWhat takeoff speed would Superman need to leap tall buildings in a single bound?88.8 miles per hour.What takeoff speed would Superman need to leap tall buildings in a single bound?Depends on how tall the building is.
