Final answer:
The acceleration of the box with a mass of 150kg and a net force of 3000N acting on it is 20 meters per second squared according to Newton's second law of motion.
Step-by-step explanation:
To determine the box's acceleration when a net force of 3000N is applied, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on the object divided by the mass of the object (a = F/m).
In this case, the mass of the box is given as 150kg, and the net force is 3000N. Plugging these values into the formula gives us:
Acceleration (a) = Net Force (F) / Mass (m) = 3000N / 150kg = 20 m/s2.
Therefore, the acceleration of the box is 20 meters per second squared.
