We had to blog our homework again...this time it was pg. 113 #22, #23, and #30. They're all about throwing/launching/falling things...
This question was about a bullet being shot horizontally from a gun...I can't really draw guns. Ah well. I realized the answer was wrong because I forgot to square root 4/9.8 ...so the right answer for time is 0.64s, and the right velocity is 207.6 m/s. I decided to blog the picture for this question anyway...the method is correct.
I liked this question because it involved tennis :]. Unfortunately I made the same mistake that I did for the previous question: I forgot to to square root 5/9.8. The right answer for distance is 31.7 m. :/
This question was about a "lovesick lad" throwing a rock at his girlfriend (it contained a love note and she had a baseball glove, but still. Why didn't they just use email?). Yes! I got this question right. I assumed up was the positive direction, so acceleration (gravity) is negative.
