Problem:
Consider a ball is kicked at an angle 0 (in degrees) from the horizontal with an initial
velocity vo m/s. Write a java program that ask the user for values of 0 and vo m/s (meter
per second) and accordingly it simulates the ball movements in very short time intervals
At millisecond (ms). You will take the time interval for measurements at a standard
interval of At = 10 ms and determine the football position Ax and Ay (i.e. x and y
coordinate). For the next iteration the new Ax and Ay will be used to update the distance.
Run the simulation until the football falls back to earth. Your program computes and
displays the position (x and y coordinates) and the velocity (v and v,) of the football to
record its dynamic-motion until it hits the ground. Calculate x and y every 10 ms but print
the values every 500 ms with the format as shown in sample runs figures below.
Create a NetBeans project named HW1_Yourld. Submit “HW1_Yourld.java" source
file to the Moodle.

Enter angle Theta between 0 and 90 degrees: 37

the x-direction is given by vox = vo cos0 and Ax = vox.At. Whereas velocity in the y-
