1. Calculate the plane’s weight:
The weight of the plane is:
2. Calculate the resistive force:
The resistive force is 0.02 times the
weight of the plane:
3. Apply the work-energy theorem:
The work done on the plane by the net force
is equal to the change in kinetic energy:
Since the plane starts from rest ():
4. Calculate the total work done by the
traction force:
The total work done by the traction force
is equal to the net work done on the plane. This work is the sum of the work
done by the traction force () and the work done by the
resistive force:
