 At time t=0, an artillery shell is launched with a vertical speed of v 0 from atop a fortress that is situated atop a mountain of height y 0. Projectile Motion2 y0y0

 y is the height (ft) of the projectile above the ground at time t (s)  g is the acceleration constant (32 ft/s 2 )  v 0 is the muzzle (initial) velocity (ft/s)  y 0 is the height of the cannon above ground (ft)  Note: We are only considering vertical height in this example. Projectile Motion3

 Assume the cannon is located 672 ft above ground level.  Assume the muzzle velocity is 656 ft/s. Projectile Motion4
