A gun fires a shell at an angle of elevation of 30 degrees with a velocity of 2*10^3m/s. What is the horizontal and vertical component of the velocity? What is the range of the shell? how high will the ball rise

Vo = 2000m/s @ 30o.
Xo = 2000*cos30.
Yo = 2000*sin30 = 1000 m/s.
Range = Vo^2*sin(2A)/g.
Vo = 2000 m/s.
2A = 60o.
g = 9.8m/s^2.
hmax = (Y^2Yo^2)/2g.
hmax = (010^6)/19.6 = 51,020 m. 
51,020m
