Answer:
a) The path is usually modeled as a parabola. (In real life, it is most definitely <em>not</em> a parabola, as air resistance and "flight" are definite factors.)
b) To get maximum height for a given speed, the ball should be launched straight up. (In real life, the kicker's effective speed will vary with launch angle.)
Step-by-step explanation:
The equations modeling air resistance and/or the fluid dynmics of an odd shape through air are impossible to solve "by hand", so we use equations that we <em>can</em> solve. For many purposes (teaching equations, functions, and solution processes, for example), the equation of a parabola is "good enough."
Vertical height is determined by vertical speed. For a given launch angle, the vertical speed is the launch speed multiplied by the sine of the angle (relative to the ground). The sine is a maximum when the angle is 90°, or straight up.

You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵
the exponent, 5, just tells you how many spaces the decimal point moved.
