Task 4- Determine the slope of the line and compute an experimental value of g from the slope value. Remember, the slope of this graph represents ½ g.
Task 5- Compute the percent error of the experimental value of g determined from the graph in part d. (Accepted value of g = 9.8 m/s2)Percent Error = (Experimental Value –Accepted Value)--------------------------------------------------- x 100%Accepted ValueAccepted value= 9.8 m/s^2(9.3m/s^2-9.8 m/s^2)---------------------------- x 100%9.8 m/s^2
