assume you mean 100 m/s
Vertical problem first:
Vi = 100 sin 30 = 50 m/s
v= Vi - g t = 50 - 9.81 t
v = 0 at top
9.81 t = 50 at top
t = 50/9.81 = 5.1 s to top
that is 10.2 s in the air including the fall
now the horizontal problem
u = 100 cos 30 = 86.6 m/s
t = 10.2 s
so range = 86.6* 10.2 = 883 meters
