homework must be in your own handwriting.
If you expect credit for your homework, then it is best to make it easily readable.

Section 2.4
Problem 1: Find the minimum speed required to throw a snowball into an open window
of a building. The window is a height h above your arm, and the building is a distance d
away from where you are standing. Hint: Check that your answer gives the expected result
in the special case that h = 0, and in the special case that d = 0. If this problem is rather
easy for you, then most likely you have made a mistake.
