Answer:
The average acceleration of the object is 0.5 cm/s^2. Answer: A)
Explanation:
Average Acceleration
The average acceleration of a moving object is the rate at which the speed changed over time in a specific period. It can be calculated as follows:
[tex]\displaystyle \bar a=\frac{v_f-v_o}{t}[/tex]
Where vf is the final speed, vo is the initial speed and t is the time.
The speed-time shows the speed starts at 0 cm/s and ends at 4 cm/s over the 8 seconds period. The average acceleration is:
[tex]\displaystyle \bar a=\frac{4-0}{8}=0.5[/tex]
The average acceleration is 0.5 cm/s^2
A) Correct. The average acceleration is 0.5 cm/s^2
B) Incorrect. The average acceleration is 0.5 cm/s^2
C) Incorrect. The average acceleration is 0.5 cm/s^2
D) Incorrect. The average acceleration is 0.5 cm/s^2
