A projectile is fired with an initial speed of 100 ft/s and angle of elevation Pi/6 (30 degrees).
A) the range of the projectile (along the x-axis)
B) the maximum height reached
C) the speed at impact
Vf^2 = Vi^2 +2a*s
Vf = Vi + a*t
Sf = Si + Vo*t + (1/2)a*t^2
(where S is any coordinate axis)
The Attempt at a Solution
I have the answers from the answer key (this is a review), and I can't seem to get any of it right.
I found s (max height) (not S), to be 127.551 seconds.
I found t = 10.2 (from launch to landing)
I found range = 883.346.
I know this isn't a hard problem, but for some reason I cannot solve it.
The answers are:
A) 625*sqrt(3)/4 ft
B) 625/16 ft
C) 100 ft/s
