6. A hunter fires a dart gun with a harmless sedative at a monkey hanging from a vine a distance h vertically above the dart gun and a distance R horizontally away from the dart gun. The hunter aims directly at the monkey and fires, but just as the hunter fires, the monkey, using its incredible spider-monkey sense, realizes what's up and drops from the vine. Does the monkey avoid the dart? Prove it mathematically (using equations).

Jane ran 72 m along the ground (distance), but only wound up 52m from where she started (displacement).

Her average speed was 72/6.8 = 10.6 m/minute, but her average velocity was 7.5 m/minute roughly northeast.

Since the magnitude of that average velocity is only about 0.28 mile per hour, I have to guess that poor Jane is on the barby right about now and the dragon is licking his chops. Poor slow Jane.
