Motion of Projectiles
Problem Statement:
The same projectiles are fired into the air with the same initial speed
35.0 m/s, but with the
different initial projection angles of
15 degrees,
45 degrees,
60 degrees,
75 degrees, and
90 degrees.
Animate the motion of the projectiles and
plot the traejctories of projectiles with 100 points for each
trajectory.
Animation
This program
projectiles.c
uses Ch QuickAnimation to
animate the motion of projectiles shown below.
From the animation, we can clearly see that
projectiles are landed at different time.
The projectile with the initial projection angle of 15 degrees
is landed the first.
The projectile with the initial projection angle of 90 degrees
is landed the last.
The projectile with the initial projection angle of 45 degrees
is landed the farthest.
The projectiles with the initial projection angles of 15 degrees
and 75 degrees are landed at the same place.
The same case for
the projectiles with the initial projection angles of 30 degrees
and 60 degrees.
Plotting
The program
projectiles.cpp
uses Ch plotting capabilities
to plot the traejctories of projectiles shown below
