Final answer:
To accelerate a 2kg rock by 12 m/s², a force of 24 Newtons is required according to Newton's second law of motion.
Step-by-step explanation:
To calculate the force needed to accelerate a 2kg rock by 12 m/s², you can use Newton's second law of motion, which states that force equals mass times acceleration (F = ma). In this case, you would multiply the mass of the rock (2kg) by the desired acceleration (12 m/s²).
So, the calculation would be: F = 2kg × 12 m/s² = 24 Newtons.
Therefore, to accelerate a 2kg rock by 12 m/s², you would need to apply a force of 24 Newtons.
