Pondering.

Is it completely pathetic when I get excited over having email in my Junk Mail folder

if memory serves (it would be easier if I had your book in front of me), F=ma, so .25 = (.16 kg) a.

a = .16/.25 (convert to whatever units are appropriate).

Once you have a, then multiply that times 2 seconds to get your average velocity. Multiply velocity times 2 seconds to get your distance. Basically, set everything up to cancel all the different units...I'm doing this in my head, so I'm not sure it's completely correct, but it should follow those lines.

thank you. you made me notice my error, I wrote 1.6 kg on my paper instead of .16, so everything was off by 10. silly me.
