We went over some of the problems from last week.

Hints
Problem 34
Remember how we solved for velocity, distance, etc. as two problems for projectile motion? You can do the same thing with energy. Analyze the horizontal energy separately from the vertical.
Problem #47
Note that there are two different sections, and the force of air resistance is different, so you need to calculate a different work for each of these sections.
Homework
Work with energy and projectile motion: The Rope Swing. Complete the handout worksheet for homework.
Yoooo, for number 3 it says POINT C is this a typo? Is it suppose to say POINT B?
Yes, that’s a typo. Should be Point B.
