Final answer:
The acceleration of the 0.75 kg model airplane with a net force of 17 N forward is 22.67 m/s².
Step-by-step explanation:
The acceleration of the model airplane can be calculated using Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). Given the mass (m) of the airplane is 0.75 kg and the net force (F) is 17 N forward, the acceleration (a) can be found using the formula:
a = F / m
By substituting the given values:
a = 17 N / 0.75 kg= 22.67 m/s²
Therefore, the acceleration of the plane is 22.67 meters per second squared.
