An artillery shell is launched on a flat, horizontal field at an angle of α = 31.5° with respect to the horizontal and with an initial speed of v0 = 266 m/s.
What is the horizontal distance covered by the shell after 9.44 s of flight?
What is the height of the shell at this moment?

bobpursley,
horizontal= 266cos31.5*t
h=266sin31.5*t4.9t^2
