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
2. #### In Topic: Help having my .jar applet show in html

Posted 6 Jul 2012

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

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..
4. #### In Topic: how to delete a particular node from xml?

Posted 14 Jun 2012

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.
