Antlion larvae lie in wait for prey at the bottom of a conical pit about 5.0 cm deep and 3.8 cm in radius. When a small insect ventures into the pit, it slides to the bottom and is seized by the antlion. If the prey attempts to escape, the antlion rapidly launches grains of sand at the prey, either knocking it down or causing a small avalanche that returns the prey to the bottom of the pit. Suppose an antlion launches grains of sand at an angle of 72 above the horizon. Find the launch speed v0 required to hit a target at the top of the pit, 5.0 cm above and 3.8 cm to the right of the antlion.

(b) How far does the ball drop between the pitcher’s hand and home plate?
Hi i have a follow up. I'm not understanding how you got the 12m or anyting like that? i added the vectors together but then you lost me. i see where the vi comes into play at(3.60). "W=12m(vf2-vi2)55.18=122.90(vf)2-(3.60)255.18=-18.79+1.45vf2vf=7.1421 m/s"
