It appears you're using the formula for acceleration, which is calculated as the force (F) divided by the mass (m). In your equation, you've given:
Force (F) = 1598 N (newtons)
Mass (m) = 12.0 kg (kilograms)
Now, you can calculate the acceleration (a) using the given values:
Acceleration (a) = Force (F) / Mass (m)
Acceleration (a) = 1598 N / 12.0 kg
Now, perform the division:
Acceleration (a) = 133.17 m/s² (rounded to two decimal places)
So, the acceleration is approximately 133.17 meters per second squared.
