Lab #9 (Shoot For Your Grade - Honors

Conclusion (20 pts)Attach to this lab a well-written paragraph which relates to the purpose of this lab. Summarize theideas that were reinforced and/or the new concepts you discovered. Report the results of yourexperiment (horizontal speed from part one, horizontal distance from part two and where you struck thetarget). Consider the importance of precision in taking data. Explain how your group was or was notprecise, using evidence from lab to support your statements. Then include at least two possiblesources of error. Remember that for every source of error listed you must provide a specific effectthat it had on your data collection and results of the lab. Be as specific as possible. (Hint – follow thesame format for writing a conclusion as lab #3)Follow up Questions: (20 pts)Directions: On a separate sheet of paper, complete the following problems. Work shown on this pagewill not be graded. Attach that sheet to this lab. Be sure to use the GUESS method and to put youranswers in proper significant figures. Remember that the chart is your givens and unknowns.1. The end of a ramp is placed at the edge of a table 1.1 meters above the floor. A marble rollsoff the ramp horizontally and strikes the floor a horizontal distance of 1.32 meters to the leftof the edge of the table. (8 pts)a. How long is the marble in the air before it strikes the floor?b. What is the initial horizontal velocity of the marble as it leaves the ramp?2. The bottom of the ramp is raised to a height of 30. cm above the height of the table. (8 pts)a. How long will the marble remain in the air before it strikes the ground?b. How far horizontally will the marble strike the floor from the edge of the ramp?3. Suppose a marble is dropped from rest from the same height and the same time as amarble which is projected horizontally off the end of the ramp with an initial velocity of 0.80m/s. Briefly explain (using complete sentences) which marble, the one dropped or the oneprojected, (4 pts)a. has the greater accelerationb. will strike the floor first, neglecting air resistance?4
