Copy the problem below into a text editor or word processor.

*

This form accepts only text so a text editor such as Notepad is fine.

*

You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer

and explanations), but note that formatting will be lost when you submit your work through the form.

*

If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be

represented correctly by the form.

*

As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as

word-processor symbols, but which gets the job done much more efficiently.

You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

The problem:

A ball accelerates at 8 cm/s^2 for 3 seconds, starting with velocity 12 cm/s.

*

What will be its velocity after the 3 seconds has elapsed?

answer/question/discussion: ->->->->->->->->->->->-> scussion:

8 cm/s^2 = v_2_ - 12 cm/s / 3s

24 cm/s^2 / s = v_2_ -12 cm/s

36 cm/s = v_2_

Final velocity = 36 cm/s

#$&*

*

Assuming that acceleration is constant, what will be its average velocity during this interval?

answer/question/discussion: ->->->->->->->->->->->-> scussion:

vAve = 36 cm/s + 12 cm/s / 2

= 24 cm/s

#$&*

*

How far will it travel during this interval?

answer/question/discussion: ->->->->->->->->->->->-> scussion:

= 72 cm
