F=20Н S=4м FnV A-?

To find acceleration (A), we need to use the formula for acceleration:

A = (Vf - Vi) / t

Since the problem statement does not provide the initial velocity (Vi) or the time (t), we cannot directly calculate the acceleration. However, if we have additional information, such as the final velocity (Vf), we can use it to calculate the acceleration.

Please provide the final velocity (Vf) or any other relevant information if available.
