Answer:
0 m/s^2
Explanation:
Use a formula to answer the question
d = r * t
The object is not changing speed at any time, or if it is we are not told. The rate is the speed.
8 = r * 1 second
8 m/sec = r
The initial speed is 8 and the final rate is 8. There is no change. So when you use this formula
a = (vf - vi)/t we get a = (8 - 8)/1 = 0
There is no acceleration because there is no change in speed.
