3. Constant Velocity Lab The real answer: Assumptions: You did not “make it easier” by making your ramp very shallow You did not bias your experiment to prove what you already believed (friction should make it stop) Real Answer: The ball has constant velocity because friction and air resistance are negligible across this short distance given the initial velocity of the ball

6. Question of the Day #13 Semiquantitative Reasoning: Draw a quick SKETCH of this situation and ESTIMATE the resultant. A row boat is crossing the bay at 5m/s following a path at 0°. A current is hitting the row boat at 35°. The current is 12m/s. What is the velocity of the row boat? Now, what would happen if a 8m/s wind coming from 90° (blowing toward 270°) hit the boat. Describe semiquantatively what would happen to the velocity of the boat. Oct 8 Today: Resolving Vector Notes Homework: -Start Ch 3 Homework #1 Ch 3 Homework #1 due Oct 13 Vector Quiz on Oct 13

13. Question of the Day #15 Practice Problem 3-4. A football is kicked at an angle θ=37.0° with a velocity of 20.0m/s. Calculate a) the maximum height, b) the time of travel before the football hits the ground, c) how far away it hits the ground, d)the velocity vector at its maximum height, and e) the acceleration vector at maximum height. Assume the ball leaves the foot at level ground and ignore air resistance and rotation of the ball.
