Ok Iam having problems again with yet something else.
The problem states that
A physics student with too much free time drops a water melon from the roof of a building. He hears the sound of the watermelon going splat 2.50s later. How high is the building? The speed of sound is 340m/s...
Iam ending up with 2 unknowns
writing it as
X- Xo = Vot + 1/2(a*t^2);
That leaves me with Vo unknown as well as the a, I can't solve it with 2 unkowns :-( and I don't know How I would get the initial velocity at stage two to solve this.[EDIT]
Forget it i got the answer I replace Vo with a*t...
I was doing this problem, and now I wonder where I went wrong
The problem states
A ball starts from rest and rolls down a hill iwth uniform acceleration, traveling 150m during the second 5.0s of its motion. How far did it roll during the first 5.0s of motion.
This is what I did
x =...

I am pretty sure I can't use that equation becasue it is no where in the chapter, I iam 100% sure they don't expect me to use something they didnt show. So there has to be another way.
They also already state the...
Ok this is what I've done.
1X = 6440m
1V = -2.68m/s
1T = 2402s (I found the time)
Then for stage 2
2V = .447m/s
2X = ?
2T = ? (These 2 unknowsn are what are throwing me off)
at first I was going to try to find the final velocity at the end of stage one
but the it never said acceleration was...
Hello I've been doing my physics homework but sadly I can't solve this problem and don't really know how to approach it. If anyone could, please guide me to how to solve this problem.
In reaching her destination, a backpacker walks with an average velocity of 1.34m/s due west. This average...
