Answer:
F_{resultant} = 1 [m/s]
Explanation:
These types of problems can be solved by means of relative velocities, where vectors (forces or velocities) are necessarily handled, these velocities depending on the velocity are added or subtracted.
Forces to the right are taken as positive and negative to the left.
[tex]F_{velocity}-F_{air}=F_{resultant}\\2-1 = F_{resultant}\\\\F_{resultant} = 1 [m/s][/tex]
