11. Question of the Day #2 Looking at the following diagrams of ramp angles, rank each ramp from lowest magnitude to greatest magnitude for each of these conditions: 1) The force of gravity causing the greatest acceleration of a ball 2) The speed of a ball at the bottom of the ramp 3) The greatest distance a ball will travel upon leaving the ramp September 4 Today’s Activities: -Finish Ramp Angle Lab Homework: -Finish Lab -Ramp Ranking Task Ramp A Ramp B Ramp C

12. September 4 Question of the Day #2 Two objects are released from rest at the top of identical ramps (see figure). The sphere rolls down the ramp. The small block slides down the other ramp without friction. Which object reaches the bottom first, and why? Hint: think of the factors affecting the speed of the car discussed yesterday.
