<PRE><B>Question 923535</B>
r=1/32v^2sin2x , where v is the initial velocity and x is the angle of elevation. r= 10,000 ft and v= 3500 ft/sec. Find the angle x.
------
10,000 = (1/32)*3500^2*sin(2x)
-----
320,000 = 12250000*sin(2x)
-----
sin(2x) = 0.03
2x = arcsin(0.03) = 1.72 degrees
x = 0.86 degrees
