Answer:
The correct option is the second option with horizontal bars at a = 6, a = -1, and a = 4 m/s²
Please find attached the table of values and a graph representing the correct option
Explanation:
The given data can be presented as follows;
Time (s), Velocity (m/s), Acceleration (m/s²)
0, -1, 6
0.5, 2, 6
1, 5, 6
0, 5, -1
0.5, 4.5, -1
1, 4, -1
1.5, 3.5, -1
2, 3, -1
2.5, 2.5, -1
3, 2, -1
0, 2, 4
0.5, 4, 4
1, 6, 4
1.5, 8, 4
2, 10, 4
From the data, and the graph the acceleration for the period from the time t = 0 to t = 1 is 6 m/s²
From t = 1 to t = 4, the acceleration is constant and equal to -1
From t = 4 to t = 6 the acceleration is also constant and equal to 4
