BIO Spin-Dry Dragonflies Some dragonflies are observed to splash into the water to bathe, and then spin rapidly to shed the water. Slow-motion video shot at 240 frames per second shows that dragonflies complete one spin revolution every 14 frames. What is the spin rate of the dragonfly in revolutions per minute (rpm)?

3.63 • Leaping the River II. A physics professor did daredevil
stunts in his spare time. His last stunt was an attempt to jump across
a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at
53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower
than the top of the ramp. The river itself was 100 m below the ramp.
Ignore air resistance. (a) What should his speed have been at the top of
the ramp to have just made it to the edge of the far bank? (b) If his speed
was only half the value found in part (a), where did he land?
