Answer:
The resulting net force is 650N
Explanation:
The force caused by air resistance against the plane's motion is called the Drag force. It acts against the motion of the plane. However, tailwinds push the plane from its tail and they apply a force is the direction of the moving plane.
The resulting force is the sum of the two forces; 450N +200N = 650N
Answer:
17.78 m/s
Explanation:
Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.
1 km = 1000 m, so 16 km is 16000 m
0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.
Thus:
average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s
