Unformatted text preview: m/s 2 Print out this graph and staple it to this worksheet before you turn it in. 2. How well does the measured value of g in Question 1 agree with the accepted value of 9.8 m/s 2 ? Compute the percent error : % error = 100 | slope 9.8 m/s 2 | 9.8 m/s 2 = % 3. Use vector components to show why the carts acceleration down the ramp equals g sin( ). Record your derivation below. 4. How well does the average value of g in Part II agree with the accepted value of 9.8 m/s 2 ? Compute the percent error : % error = 100 | average 9.8 m/s 2 | 9.8 m/s 2 = % 5. Which method, Part I or Part II, yields a more accurate measurement of g ? Explain in detail below why you believe this is so....
