Tony Stark's personal assistant Pepper tries to escape an automated drone by running horizontally with a speed of 6.00 m.s off the roof of a 35.0 m tall building. Tony Stark who has been standing right below the edge of the roof, tries to catch her about 1.5 m above street level. Ignore air resistance. How fast must he be running at a constant speed in order to catch pepper? How far from the building will he catch her?

I worked out some of the work, I want to make sure its correct.
