An artillery shell is launched on a flat, horizontal field at an angle of A = 41.9° with respect to the horizontal and with an initial speed of v0 = 206 m/s. What is the horizontal velocity of the shell after 18.03 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.)
What is the vertical velocity of the shell at this moment?
