Exercises

Exercise 1a

Exercise 1b

Exercise 2

Draw a square using a black pen (reasonable side length).

Draw a solid red circle that is completely inside the square.

Draw a straight horizontal line through the center of the circle

Exercise 3

Rocket program continued

Change the title to Rocket program created by (enter your name)

Using labels and text boxes as appropriate, prompt the user to enter

        Ø The flight time

        Ø The initial velocity

        Ø The launch angle

Draw an explosion at the point of impact. Simulate the explostion using a variation of the starburst example - centered at point of x axis intercept

Note that I have prevented the rocket from entering the ground. Write code to prevent it from exceeding the top of the y axis

        and the end of the x axis.

Use code to place a title for the program on the form near the top (not same task as first bullet above)

At approximately the mid point of the horizontal axis, cause a square with blue borders to be placed randomly in the vertical

        direction so that It varies from 10 to the length of the y axis. The length of a side should be no larger than 1/10 the length of the x axis

If the rocket hits this target, a message box should announce "ouch" or some appropriate message.

If the rocket misses this target, a message box should announch "missed" or some appropriate message.

Exercise 4

This is a continuation of Rocket Program, Part b

Change the above to incorporate the following

       Ø Use Input Boxes to prompt the user for the time of flight, launch angle, and initial velocity.

       Ø If the rocket hits the target, then draw a starburst at the point of impact such that the starburst does not completely obliterate (hide from view) the box (or

             target). You do not need a message block to indicate the hit.

       Ø If the rocket misses the target, then draw a starburst at the point of impact with the x axis. Only the top part of the starburst should be shown.

       Ø Place an appropriate title at the top of the trajectory (using code) and also label the form (using code).
