<h2>Hello!</h2>
The answer is:
The correct option is the option D
To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:
Where:
is the final speed.
is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:
Then, using the formula to isolate the acceleration, we have:
Now, substituting we have:
Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:
Hence, the correct option is the option D
Have a nice day!
