Unformatted text preview: fence, it will strike the ground in 0.5 s (so that the total "fall-time" equals the "rise-time"). Since the horizontal component of velocity in a projectile-motion problem is constant (neglecting air friction), we find the original x-component from 97.5 m = v x (5.5 s) and then apply it to that final 0.5 s. Thus, we find v x = 17.7 m/s and that after the fence x = (17.7 m/s)(0.5 s) = 8.9 m....
