Answer:
Impulse = change in momentum w bounce
There are 2 impulses acting. Recoil of the fan going the negative direction and the impulse of the air bouncing off the sail. The greater impulse will bounce so the direction will be to the right moving the craft.
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


Answer:
The answer is 4200 J.
Explanation:
The formula of work done is, W = F×D where F is the force of an object and D is the distance. Then you just substitute the values into the equation :
W = F×D
F = 42N
D = 100m
W = 42 × 100
= 4200 J
