Homework Help: Hunter diring at a monkey hanging from a vine.

  1. Oct 6, 2007 #1
    1. The problem statement, all variables and given/known data
    A hunter fires a dartgun with a harmless sedative at a monkey hanging from a vine a distance h vertically above the dartgun and a distance d horizontally away from the dartgun. The hunter aims directly at the monkey and fires with an inital velocity Vo at an angle theta above the x axis. But just as the hunter fires, the monket drops from the vine. Assume zero air resistance. a)find the x and y components of the initial velocity of the dart. b) find the horizontal displacement, Xdart, and vertical displacement, Ymonkey, of the monket after a time t. c) find the horizontal displacement, Xmonkey, and vertical displacement, Ymonkey, of the monkey after a time t. d)find that the condition needed for the dart to hit the monkey is tan theta = h/d e)what can be inferred from (d)?

    2. Relevant equations
    The four equations of kinematics for constant acceleration:
    1.) V=Vo+at
    2.) X=1/2(Vo+V)t
    3.) X=Vot+1/2at^2
    4.) lVl^2= lVol^2 +2a times X

    3. The attempt at a solution
    I do not know how to even start this problem off, I am so confused! I need to have this done by Monday morning so any help would be greatly appreciated.

    What about the equations for projectile motion.

    I added the equations to the original post now.
