HW 6 SNAFU

I accidentally made the HW due at noon today instead of midnight ... stupid am and pm. As a result, I have just extended the deadline until noon tomorrow in case you need some more time.

HW3 problem #2

As one of you pointed out already, problem 2 on the current homework set is a bit ambiguous until you reveal the first hint. Or, as your classmate put it "[It] doesn't make sense unless you use the 1st hint. I thought it was in the air at 0.8m not on the water."

To clear up the ambiguity, I'll just give you the first hint on the problem:

Hint 1. How to approach the problem: This problem involves projectile motion. A drop of water is launched at a certain angle above the surface, and you need to calculate the initial speed required to hit the target. Note that the target is an insect floating over the surface of the water.

Today's lab ... revised

Due to a scheduling mix-up with the PH105 class, we'll do the friction lab today, and force on Wednesday.

Here is the friction lab writeup.
