Homework Statement
A kindly zookeeper, concerned about the health of her prize koala, aims a dart gun at the koala who is sitting in the tree munching on eucalyptus leaves. The koala, feeling a bit under the weather and sensing impending doom, perks up and watches the zookeeper aiming her gun. The wily koala drops from her perch when she sees the dart gun fire and falls to the ground. Does the koala get to the ground to run and hide, or does the dart hit the koala and put it to sleep for a checkup? Prove it with equations and words below. Assume the following: the koala has mass m, the zookeeper (mass M) has perfect aim and is aiming right at the stationary koala (angle theta from the horizontal) in the tree from a distance D away, the koala drops at the same clock reading (or instant) the dart leaves the gun, the koala is height h above the end of the dart gun in the tree, the dart leaves the muzzle of the gun with speed vi which is more than sufficient to reach the koala in the tree. Air friction is negligible.
Homework Equations
The Attempt at a Solution
I don't think mass has any affect on this problem.
However I'm not sure how to start it. is seems like a special relativity problem as well.
hints or helps would be helpful?
