1. -/20 points A group of students, performing the same "Uniform Circular Motion" experiment that you performed in lab, obtained the following results. r (m) m (kg) t (s) 0.1825 0.1007 57.30 D.2430 0.14668 50.00 D.2610 0.16036 52.06 0.2980 0.18848 53.85 0.3425 0.2223 53.22 For this table, r is the distance from the center of rotation to the radius indicator (i.e., the post that marks the position of the center of the bob during rotation), m is the total hanging mass (including the hanger), and t is the time required for 50 complete rotations. (a) Use Excel to construct a spreadsheet that show the following. (You will not submit this spreadsheet. However, the results will be needed later in this problem.) (i) the above data (ii) all calculations needed to compute the acceleration, a, for each trial HINT (iii) a graph of m g vs a HINT (iv) Use the trendline option to draw the best fit line and determine its slope. HINT (b) Report this value below. mass of the bob = (No Response) 0.18 kg
