I already figured this one out, but I thought at least one person would get a laugh out of this one.

Suzy drops a rock from the roof of her house. Mary sees the rock pass her 4.7m tall window in 0.168 sec. The acceleration of gravity is 9.8m/s/s.

From how high above the top of hte window was the rock dropped? Answer in units of m.

This problem was worded funny, but basically it's saying the rock passed through 4.7m in .168 seconds. From this, I calculated the initial and final velocity of the rock as it traveled through the range of the window. The initial velocity was 27.2m/s and the final was 28.8m/s.

From here, I found out how many meters up the rock would've been dropped from in order to reach the speed of 27.2m/s when it first came into sight of the window. Our teacher usually tells us to evaluate our answers to see if they make common sense, and when I solved for this problem my answer came up as 37.6m.

Apparently, this girl was on the roof of her house 37meters up. If I had a house that big, I'd probably have better things to do than drop rocks from the roof

After typing all that, it really isn't as funny as I thought it would be, but I still got a good chuckle out of it
