Answer : F = 3.3 N
Explanation :
It is given that :
Mass of model airplane, m = 0.3 kg
Acceleration, [tex]a=11\ m/s^2[/tex]
According to Newton's second law :
Force acting on an object is the product of mass and the acceleration with which it is moving.
F = m a
So, [tex]F=0.3\ kg\times 11\ m/s^2[/tex]
[tex]F=3.3\ N[/tex]
So, the net force on the model airplane is 3.3 N.
