The car's forward motion is opposed by the friction between the road and the tires and by the resistance of the air.
Answer:
A 10 N force pointing up
Explanation:
If the net acceleration of the object is horizontal pointing to the right, that means that all vertical forces must have canceled out, and the only ones "unbalanced" are the horizontal ones (10 N to the right minus 5 N to the left giving a net force of 5 N to the right).
Since they mentioned only one vertical force pointing down (10 N), there must be another one of same magnitude but pointing in opposite direction (up).
Then there must also be a 10 N force pointing up acting on the object.
Initially its moving with tail wind so here the speed of wind will support the motion of the plane
so we can say
now when its moving with head wind we can say that wind is opposite to the motion of the plane
now by using above two equations we can find speed of palne as well as speed of wind
