1 meter up, 1 meter to the left and then 1 metter down.
It goes 1 meter up and 1 meter down, so its in the same place. The only displacement is
1 meter to the left.
Look at picture:

Answer:
C. the top line represents a greater velocity
Explanation:
The graph is a distance - time graph.
The distance is on the y-axis and time is on the x - axis.
For this graph, the slope is the velocity.
- The steeper the line, the higher the velocity or the higher the slope.
- Since the upper line is steeper, it will have a higher slope
- Hence a greater velocity
The lower line is not so steep and its slope is lesser compared to the upper one.

Define
u = 16 m/s, the vertical launch velocity
g = acceleration due to gravity, measured positive downward
s = vertical distance traveled
t = 21.2 s, total time of travel.
The vertical motion obeys the equation
s = ut - (1/2)gt²
When the rock is at ground level, s = 0.
Therefore
(16 m/s)(21.2 s) - 0.5*(g m/s²)*(21.2 s)² = 0
339.2 - 224.72g = 0
g = 1.5094 m/s²
Answer:
The acceleration due to gravity is 1.509 m/s² measured positive downward.
