Antlion larvae lie in wait for prey at the bottom of aconical pit about 5.0 cm deep and 3.8 cm in radius. When asmall insect ventures into the pit, it slides to the bottom and isseized by the antlion. If the prey attempts to escape, the antlionrapidly launches grains of sand at the prey, either knockingit down or causing a small avalanche that returns the preyto the bottom of the pit. Suppose an antlion launches grainsof sand at an angle of 72° above the horizon. Find the launchspeed v0 required to hit a target at the top of the pit, 5.0 cmabove and 3.8 cm to the right of the antlion.
