net force=mass*a
forwardforce-resistiveforce=ma
8-resistiveforce=.25*1.8
solve for resistive force.
Then air exerts a forward force of 8 N on the
propeller of a 0.25 kg model airplane.
If the plane accelerates forward at 1.8 m/s^2,
what is the magnitude of the resistive force
exerted by the air on the airplane?
Answer in units of N.
