Final answer:
The acceleration of the crate is 9.8 m/s².
Step-by-step explanation:
The acceleration of the crate can be calculated using the equation a = g, where g is the acceleration due to gravity. On Earth, the average value of g is approximately 9.8 m/s².
Since the crate is dropping vertically downward, its acceleration is in the same direction as the acceleration due to gravity. Therefore, the acceleration of the crate is 9.8 m/s².
