A hunter aims his gun and fires a bullet directly at a monkey. At the instant the bullet is fired, the monkey drops. The minimum speed for the bullet to hit monkey is..?
*November 9, 2013*

**Physics 12 Kinematics**

The bullet must go horizontally a distance, Dx, so Dx = Vh / t or t = Vh / Dx = VcosA / D and Vup = VsinA + gt .... or t = (Vup -VsinA) /g .... sub VcosA /D = (Vup -VsinA) /g .... V = D(Vup -VsinA)(g cosA)
