How do you do each step of this problem? Please do this thoroughly so I can learn how to do similar problems. 0.5/2 points Previous Answers SerCP10 2.P017 My Notes A graph of position versus time for a certain particle moving along the x-axis is shown in the figure below. Find the instantaneous velocity at the following instants. x (m) t (s) -2 1 2 3 4 5 6 7 (a) t 1.00 s m/s 5.00 (b) t 3.00 s The response you submitted has the wrong sign. m/s the beginning and check each step carefully, ms (c) t 4.50 s Rework Your response differs significantly from the correct answ (d) 7.50 s The response you submitted has the wrong sign, m/s Need Help?

Explanation / Answer

We know that the velocity at any instant is given by slope in position time graph

b) v = [5-10]/[4-2] = -2.5 m/s

c) v = [5-5]/[5-4] = 0 m/s

d) v = [0 - -5]/[8-7] = 5 m/s
