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.

Step-by-step explanation:
3 milliliters.
Step-by-step explanation:
3 because 12÷4=3 and he made enough for 4.
54 l= 112/8.4x54= 720 miles
Answer:5
Step-by-step explanation:
Form the equation 27.75n+5.50=144.25
Subtract 5.50 from 144.25.
144.25-5.50=138.75. Now you have 27.75n=138.75. Divide 138.75 by 27.75, 138.75/27.75=5. So n=5
