A projectile is fired horizontally from a gun that is 63.0 m above flat ground. The muzzle velocity is 250 m/s.(adsbygoogle = window.adsbygoogle || []).push({});

(a) How long does the projectile remain in the air? (in seconds)

I got 3.96 s

(b) At what horizontal distance from the firing point does it strike the ground? ( in meters) I got 19.44 m

(c) What is the magnitude of the vertical component of its velocity as it strikes the ground? I got 187 m

because v(x) is a constant and v sub zero is zero in the vertical direction

i did 63=.5(9.8)t^2
