In a position-time graph, the slope of the
line represents the velocity of the object. The greater the magnitude of the
slope, the greater the speed of the object.
Calculate the slope (and thus the speed)
for each section:
Section BC:
The initial position m at s and the final position m at s.
The slope m/s. The speed m/s.
Section DE:
The initial position m at s and the final position m at s.
The slope m/s. The speed m/s.
Section FG:
The initial position m at
