A hunter is testing 3 new arrowheads. He hangs a watermelon from tree using a rope. When the arrow hits the watermelon it swings upward. The maximum angle that the rope makes with the vertical is different for each arrowhead the hunter tests. All the arrows have the same mass m and is shot with the same velocity v0. Each of the 3 arrowheads are
made of different materials, and as a result, react differently when striking the watermelon.
Pointy arrow: Strikes the watermelon and remains embedded, while the watermelon swings to angle Opointy
Through arrow: Goes all the way through the watermelon and continues traveling
away from the hunter, while the watermelon swings to angle Othrough
Bouncy arrow. Bounces off the watermelon back toward the hunter, while the watermelon swings to angle bouncy
Rank the three angles 8 pointy. Othrough and Obouncy from greatest to least. Thoroughly explain your reasoning for your ranking below.
