A park patron got their kite stuck in a tree. After several minutes of messing with the branches, the kite finally drops from the branch. It took the kite 6 seconds to reach the ground. (g = 9.81 m/s ^ 2) What was the kite's velocity just before it hit the ground?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
