I'm Mr. Collins, the most dangerous bore of the country!
Hey guess what! I am Mr. Collins in a Pride and Prejudice play at my school. Mrs. Stark (thats my drama club director) said i could've made a wonderful person acting as anyone in the play but i was put as Mr. Collins because he required a little higher level of acting, because he was a more specific, and harder, character! I get to be the most dangerous bore of the country according to the script. But i actually am a pretty halarious bore for that matter!

physics problem!
here's a really hard physics problem for ya! I solved it, maybe you can!
here it is:
A rock is dropped off a cliff into the ocean. The sound of the splash is heard 3.2 seconds after it is dropped. Assuming the speed of sound is 340 m/s and gravity accelerates the rock at 10 m/s^2, what is the height of the cliff? (neglecting air resistance)
help:
Find givens:
Time: 3.2sec
Sound spd.: 340m/s
Gravity: 20m/s^2
Unknowns:
Time of sound: ?
Time of fall: ?
height: ?
DRAW A DIAGRAM!
Eqn's: You'll need 2 of them! Find out which ones!(all require assumed constant acceleration)
x=xo+vot+(.5)g(t^2)
v=v+at
(avg.)v=(vo+vf)/2
(avg.)v=d/t
GOOD LUCK! HAVE FUN!
