A car moves along an x axis through a distance of 300m, starting at rest (at x=0), and ending at rest (at x=500m). Through the first ¼ of that distance, its acceleration is 2.15 m/s2
. Through the
next ¾ of that distance, its acceleration is -0.810 m/s2.
.
Find A) the velocity after travelling ¼ of the total distance
B) the time of travelling ¼ of the total distance
C) the time of travelling the remaining ¾ of the total distance
D) the total time of the entire travel.
E) Plot the graph of x-t and v- t of the motion
