physics horizontal and vertical velocity question

Question

An artillery shell is launched on a flat, horizontal field at an angle of α = 32.8° with respect to the horizontal and with an initial speed of v₀ = 224 m/s. What is the horizontal velocity of the shell after 14.37 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?

Answer 1

Initial horizontal velocity = 224cos32.8=188.3 m/s is a constant

Initial vertical velocity=224sin32.8=121.3 m/s

Vertical velocity @ 14.37 seconds = 121.3-g(14.37) = -19.7 m/s

Since the shell has impacted the ground sooned than 14.37 seconds, both the horizontal and vertical velocity are zero at 14.37 sec
