Question

Use the exact values you enter to make later calculations.

A group of students performed the same "Newton's Second Law" experiment that you did in class. For this lab, assume g = 9.81 m/s2. They obtained the following results:

m1(kg) t1(s) v1(m/s) t2(s) v2(m/s) 0.050 1.2000 0.2500 1.8108 0.3849 0.100 1.2300 0.3240 1.6360 0.6412 0.150 1.1500 0.3820 1.4768 0.8120 0.200 1.1100 0.4240 1.3935 1.0067 Use the exact values you enter to make later calculations. A group of students performed the same "Newton's Second Law" experiment that you did in class. For this lab, assume g = 9.81 m/s2. They obtained the following results: where m1 is the value of the hanging mass (including the mass of the hanger), v1 is the average velocity and t1 is the time at which v1 is the instantaneous velocity for the first photo gate, and v2 is the average velocity and t2 is the time at which v2 is the instantaneous velocity for the second photo gate. Use Excel to construct a spreadsheet to do the following. (You will not submit this spreadsheet. However, the results will be needed later in this problem.) Enter the above data. Compute the acceleration, a, for each trial. Create a graph of the hanging weight m1g vs. the acceleration. Use the trend line option to draw the best fit line for the above data and determine the slope and y-intercept from it. Use the information you obtained from your graph to determine the total mass of the system M = m1 + m2. Using the information you obtained in parts (a) and (b), predict what the value of the acceleration would be if the value of the hanging mass were increased tom1 = 0.50 kg. a =

Explanation / Answer

acceleration=(v2-v1)/t2-t1;

calculate the same for all the values.

for the graph m1g vs acceleration.

slope and y-intercept can be found using least square fit method..

formulae are..

Slope(b) = (N?XY - (?X)(?Y)) / (N?X2 - (?X)2)

Intercept(a) = (?Y - b(?X)) / N

here X refers to acceleration and Y refers to m1*g
