Question
A graph of position versus time for a certain particle moving along the x axis is shown in Figure P2.6. Find the average velocity in the following time intervals. (The horizontal axis is marked in increments of 10 s and the vertical axis is marked in increments of 20 m.)
(b) 0 to 40.00 s =______ m/s
(c) 20.00 to 40.00 s=______ m/s
(d) 40.00 to 70.00=_______ m/s
A graph of position versus time for a certain particle moving along the x axis is shown in Figure P2.6. Find the average velocity in the following time intervals. (The horizontal axis is marked in increments of 10 s and the vertical axis is marked in increments of 20 m.)Explanation / Answer
b) average velocity = 50 / 40 = 1.25 m/sec
c) (50 - 100 ) / 20 = - 2.5 m/sec
d) ( - 50 - 50 ) / 30 = -3.33 m/sec
