In this chapter, we will see both applications and applets. We will try to cover problems from different walks of life.
When we see a fielder standing on boundary line, throwing the ball straight into the gloves of the wicket keeper, we think that he is a genius. Well, he may or may not be, but one thing is sure. He has done his college physics seriously. A projectile starting at an angle of 45 degrees travels farthest, before hitting the ground.
Let us develop an applet to show the trajectory of a projectile.
Problem: Write an applet to show the trajectory of a projectile.
Solution: Let us assume the following:
When a projectile starts, it has velocities both in horizontal and vertical direction. ...
