Design a class Cannonball to model a cannonball that is fired into
the air. A ball has • A flight time after fired. • An x- and a
y-position. • An x- and a y-velocity. Supply the following member
functions: • A constructor with the appropriate variables
initialized. Assume the cannonball starts at the origin (0,0). • A
member function move(double sec) that moves the ball to the next
position for a given time increment (sec). Using the projectile
motion formula and assuming negligible air resistance. Considering
the gravitational acceleration of –9.81 m/sec2. 1. First compute
the distance traveled in seconds, using the current velocities,
then update the x- and y-positions. 2. Then update the y-velocity;
the x-velocity is unchanged. 3. Move should not print anything to
the console. • A member function shoot whose parameters are the
angle a and initial velocity v 1. Compute the x-velocity as
v*cos(a) and the y-velocity as v*sin(a). 2. Then keep calling move
with a time interval of 0.1 seconds until the y-position is ≤ 0 3.
Display the (x, y) position and flight time after every 10 moves
and when the ball hits the ground. Use setw(8) and setprecision(2)
to format the positions; Use setw(4) and setprecision(1) to format
the times. Use this class in a program that prompts the user for
the starting angle and the initial velocity. Then call shoot.
Requirements: 1. You must submit three c++ files: 1. one header
(.h) file containing the declaration of the class, 2. one .cpp file
containing the member functions, 3. one .cpp file containing the
main function. 2. Both move and shoot should be void functions. The
only input to either should be (double sec) to move. 3. Return a
termination message when the ball hits the ground 4. Please test
for an angle of 30° and 100 m/sec launch velocity. All units can be
assumed to be metric.
