5. Vector Addition Quiz #2: Millenium Falcon dodging Asteroids! Han Solo is being pursued by tie fighters through an asteroid field…a large asteroid is approaching so he fires a side thruster to dodge it. Han Solo is being pursued by tie fighters through an asteroid field…a large asteroid is approaching so he fires a side thruster to dodge it. The side thruster gives the Falcon a velocity of 76 mph (34 m/s) at 83 degrees West of North. The side thruster gives the Falcon a velocity of 76 mph (34 m/s) at 83 degrees West of North. The Falcon already has a forward velocity of 245 mph (109.5 m/s) at 6 degrees West of North from the main thrusters. The Falcon already has a forward velocity of 245 mph (109.5 m/s) at 6 degrees West of North from the main thrusters. What is the resulting velocity (speed and direction) of the Millenium Falcon as it dodges the asteroid? What is the resulting velocity (speed and direction) of the Millenium Falcon as it dodges the asteroid?

6. Tues Bellwork10-27-09 Pick up a Ch. 3 Review Sheet (by bins) Pick up a Ch. 3 Review Sheet (by bins) Check your answers to 3-3 Math Skills #’s 1-5 (on the board) Check your answers to 3-3 Math Skills #’s 1-5 (on the board) Check Preliminary Questions Answers: Check Preliminary Questions Answers: 1. Time for each band through the photogate 2. Linear graph (y = mx + b)  (v = at + v 0 ) 3. Nope! Still the acceleration of gravity! But the final velocity will be different.

7. Objective TSWBAT measure the acceleration of a freely falling body (g) to better than 0.5% precision using a “Picket Fence” and a Photogate TSWBAT measure the acceleration of a freely falling body (g) to better than 0.5% precision using a “Picket Fence” and a Photogate
