The distance a projectile travels when fi red at an angle u is a function of time and can be divided into horizontal and vertical distances (see Figure P12.25 ), given respectively by
                                           ![]()
And
                                          ![]()
Â
where
horizontal = distance traveled in the x direction
vertical = distance traveled in the y direction
V0 = initial velocity of the projectile
g = acceleration due to gravity, 9.8 m>s2
t = time, s.
Suppose a projectile is fi red at an initial velocity of 100 m/s and a launch angle of π/ 4radians (45°). Use ezplot to graph horizontal distance on the x-axis and vertical distance on the y-axis for times from 0 to 20 seconds.
