A person who walks for exercise produces the position-time graph shown. Calculate the average velocity, including sign, for (a) segment A. (b) segment B. (c) segment C, and (d) segment D. +1.25 +1.00

A person who walks for exercise produces the position-time graph shown. Calculate the average velocity, including sign, for (a) segment A. (b) segment B. (c) segment C, and (d) segment D. +1.25 +1.00

Theaverage velocityfor (a) segment A is 1.67 m/s (positive), (b) segment B is 0 m/s (no velocity), (c) segment C is -1.67 m/s (negative), and (d) segment D is 3.33 m/s (positive).The average velocity can be obtained using the following formula:Average velocity = change in position / change in timeWhere change in position is the difference between final position and initial position. Change in time is the difference between final time and initial time.Segment A:Initial position = 0 mFinal position = 25 mInitial time = 0 sFinal time = 15 sChange in position = final position - initial position= 25 m - 0 m= 25 mChange in time = final time - initial time= 15 s - 0 s= 15 sAverage velocity of segment A = change in position / change in time= 25 m / 15 s= 1.67 m/s (positivevelocity, because the person is moving in the positive direction)Segment B:Initial position = 25 mFinal position = 25 mInitial time = 15 sFinal time = 30 sChange in position = final position - initial position= 25 m - 25 m= 0 mChange in time = final time - initial time= 30 s - 15 s= 15 sAverage velocity of segment B = change in position / change intime= 0 m / 15 s= 0 m/s (no velocity, because the person is not moving)Segment C: Initial position = 25 mFinal position = 0 mInitial time = 30 sFinal time = 45 sChange in position = final position - initial position= 0 m - 25 m= -25 mChange in time = final time - initial time= 45 s - 30 s= 15 sAverage velocity of segment C = change in position / change in time= -25 m / 15 s= -1.67 m/s (negative velocity, because the person is moving in the negative direction)Segment D:Initial position = 0 mFinal position = 50 mInitial time = 45 sFinal time = 60 sChange in position = final position - initial position= 50 m - 0 m= 50 mChange in time = final time - initial time= 60 s - 45 s= 15 sAverage velocity of segment D = change in position / change in time= 50 m / 15 s= 3.33 m/s (positive velocity, because the person is moving in the positive direction)Theposition-time graphis given below:To learn more onposition-time graph:brainly.com/question/25225415#SPJ11...
