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
