Question

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 . What should be his minimum roof top speed , in m/s , so that he can successfully make a jump ?
Vo = Hor. speed.
R = 6.2 m. = hor. range.

0.5g*T^2 = 4.8 m.
4.9*T^2 = 4.8,
T = 0.99 s.

R = Vo * T = 6.2 m.
Vo * 0.99 = 6.2,
Vo = ?
