1. A soccer ball is kicked by Kenneth 16 points from the ground at an angle of 50°
with an initial velocity of 38.0 m/s.
(a) How far does it travel towards
the opponent's base horizontally
and vertically? Find the (b) time of
flight, (c) maximum height attained
by the soccer ball, (d) range.

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.)
