The Week of 10/29-11/2

• Mon 10/29:  Check off Projectile Problems 1-7 (8+9 extra credit) and go over.  Projectiles launched at an angle.  Problems 10-12 on Projectile Worksheet.
• Tues/Wed 10/30-10/31:  Range Equation.  Rocket Lab.  Calculate initial velocity of the rocket, time in the air, and height for 4 different angles.  Problems 10-15 on Projectile Worksheet for Thurs/Fri.  "Brick or Treat" lab.

Vector Worksheet Answers

These are the final answers.  All of these (especially the problems on the back of the worksheet) can be greatly influenced by one incorrectly converted angle or a calculator that is in radians instead of degrees.  Come in and check with me if you are having trouble getting these answers and I should be able to help you figure out where you went wrong.  Also, remember that slight variations in answers may occur if you round as you go.
