Answer :
Final answer:
The average acceleration of the object is 4.94 m/s².
Explanation:
To calculate the average acceleration of the object, we can use the formula:
average acceleration = (final velocity - initial velocity) / time
Given that the initial velocity is 4.00 m/s at t = 3.00 s, and the final velocity is 28.7 m/s at t = 8.00 s, we can substitute these values into the formula:
average acceleration = (28.7 m/s - 4.00 m/s) / (8.00 s - 3.00 s)
Simplifying the equation:
average acceleration = 24.7 m/s / 5.00 s
Therefore, the average acceleration of the object is 4.94 m/s².
