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 = 250 m/s. What is the horizontal velocity of the shell after 21.84 s of flight? (Neglect air friction. Use the coordinate system where the x-axis is horizontal and points to the right; and the y-axis is vertical and points up.) (in m/s)
A) 1.71 × 10²
B) 2.13 × 10²
C) 2.66 × 10²
D) 3.33 × 10²
E) 4.16 × 10²
F) 5.20 × 10²
G) 6.51 × 10²
H) 8.13 × 10²
