The net external force on the propeller of a 3.9 kg model airplane is 6.8 N forward.
What is the acceleration of the airplane?
Hey, F = m a here as well
To find the acceleration of the airplane, 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 it divided by its mass.
The mass of the airplane is given as 3.9 kg, and the net external force acting on the airplane is given as 6.8 N forward. So, we can use the formula:
Acceleration = Net force / Mass
Substituting the values, we get:
Acceleration = 6.8 N / 3.9 kg
Now we can calculate the acceleration:
Acceleration = 1.74 m/s^2
Therefore, the acceleration of the airplane is 1.74 m/s^2.
