Math Problem Statement
On level ground a shell is fired with an initial velocity of 30m/s at30 degrees above the horizontal and feels no appreciable air resistance. a) Find the horizontal and vertical components of shell's initial velocity. b) How long does it take the shell to reach the highest point? c) Find the maximum height above the ground. d) How far from firing point does the shell land? e At its highest point find the horizontal and vertical components of its acceleration and velocity.

Formulas
Horizontal Velocity: v0x = v0 * cos(θ)
Vertical Velocity: v0y = v0 * sin(θ)
Time to Highest Point: t_up = v0y / g
Maximum Height: h_max = v0y * t_up - (1/2) * g * t_up^2
Range: R = v0x * t_total
Total Flight Time: t_total = 2 * t_up
