"100 m" does not have the proper dimension for a velocity. Do you mean 100 m/s? If so, the vertical component of Vo is

Vyo = Vo sin60 = 86.6 m/s

The stone will rise an additional distance H such that

gH = (Vyo)^2/2

H = 383 m.Max hweight above ground will be H + 100 = 483 m.

Time to reach max height = Vyo/g = 8.8 seconds.

For the total time of flight, add to that the time it takes to fall 483 m.
