A stuntman plans to run across a roof top and then horizontally off it to a land on the roof of the next building . The roof of the next building is 4.8 m below the first one and 6.2 m away from it . Can he make the jump if his maximum rooftop speed is 4.5 m/s?

Vo = 4.5 m/s, horizontally.
0.5g*t^2 = 4.8 m.
4.9*t^2 = 4.8,
t = 0.99 s. = Fall time.
Range = Vo * t = 4.5 * 0.99 = 4.45 m.
Required range = 6.2 m. No, he will not make the jump!
