Problem 6P

(Note: In Problems, assume a number like 6.4 is accurate to ; and 950 is unless 950 is said to be “precisely” or “very nearly 950, in which case assume 950 )

What is the percent uncertainty in the measurement 3.76 0,25 m?

Solution 6P STEP 1:- The coordinate system for this problem could be drawn as, The diagram shows, +ve x- axis is the east direction, -ve x-axis is the west direction, O is the origin, At the -ve x axis one intersection is there which is Mulberry Road. STEP 2:- The car ends up at 14mi west which is shown by the circle at the -ve x-axis. So the position is -14. The car reached this point after it undergoes a displacement of -23mi. So it must have started from the point, 23-14= +9 miles. Because if it will start from +9 point on the +ve x-axis, then after a displacement of -23miles it would reach -14miles at the -ve x-axis. CONCLUSION: So the point representing +9 was the starting point and the car must have started at right side of mulberry road. When the car started it was 23 miles away from the intersection (mulberry road).
