Your visual is of great aid, but you are using it wrong!

So you know that A + B = 100

Remember that A and B is distance here.

What is the distance after the runner stopped accelerating? S = V * T
This translates into: B = v * 8.6

What is the distance during acceleration? S = 2(u + v) / t
This translates into: A = 2 (8,8 + v ) / 2 = 8,8 + v

Putting it all together:
100 = 8,8 + v + v*8,6

=> 91,2 = 9,6v
=> v = 91,2 / 9,6 = 9,5 m/s

The information in the "code" attribute should not be .class.

Instead it is the package.location.YourClass

For your case this should be: Pong.copy.Main

In other words:

<Applet
Code="Pong.copy.Main"
archive="BrickBreaker.jar"
width=500
Height=500>
</Applet>

First thing I see is no closing bracket for the else on line 8.

But I suspect you have only given us part of your code, which makes it very hard to to know where your line 71 is..

What you should look at is the method for a Node that is called "removeChild".

However you seem to be doing a lot of things which doesn't make sense in your for loop. You should look into separating pieces of code into methods.

Hello,

The reason is simply: "The values 12! and 20! are the largest factorials that can be stored in, respectively, the 32 bit and 64 bit integers commonly used in personal computers."
