Design a class Cannonba ll to model a cannonball that is fired into the air. A ball has • An x- and a y-position. • Anx- and a y-velocity. Supply the following methods: • A constructor with an x-position (the y-position is initially 0) • A method move(double sec) that moves the ball to the next position (First compute the distance traveled in sec seconds, using the current velocities, then update the x- and y-positions; then update the y-velocity by taking into account the gravitational acceleration of –9.81 m/s²; the x-velocity is unchanged.) • Methods getX and getY that get the current location of the cannonball • A method shoot whose arguments are the angle a and initial velocity v (Com- pute the x-velocity as v cos a and the y-velocity as v sin a; then keep calling move with a time interval of 0.1 seconds until the y-position is 0; call getX and getY after every move and display the position.) Use this class in a program that prompts the user for the starting angle and the initial velocity. Then call shoot.
