Final answer:
The acceleration of a 10kg box being pushed with a force of 20N is 2 m/s^2, as calculated using Newton's second law of motion (F = ma).
Step-by-step explanation:
When pushing a box with a force of 20N that has a mass of 10kg and solving for acceleration, we use Newton's second law of motion (F = ma). Rearranging the equation to solve for acceleration (a = F/m), we get:
- Force (F) = 20N
- Mass (m) = 10kg
- Acceleration (a) = F/m = 20N / 10kg
Therefore, the acceleration (a) = 2 m/s^2. The correct answer is b) 2 m/s^2.
