Homework Statement
The question says this: Use one dimension to solve the problem.
A woman drops a rock off a bridge (0=270 degrees-- wasn't sure how to type the line through the zero, sorry!) and it takes 2.3 seconds for the rock to hit the water below. How tall is the bridge?
Homework Equations
Delta x=Vot+one half at^2
The Attempt at a Solution
I have this written out:
Delta x=Vot+one half at^2
Delta x=(0)*(2.3 sec) plus one half times (-9.8 m/sec^2) times (2.3)^2
Delta x= one half times (-9.8 m/sec^2) times (5.3 sec^2) ((the sec^2 is slashed out))
Delta x=26 m
I then made the 26 negative, as I read it needs to be.
When I was working the problem, I wasn't sure what to do with the 0=270 degrees portion. I'd like to know if I did this correctly, and if not, what I did incorrectly/what the fix for it is. Thank you! :)
