Answer:
557.7Nm
Explanation:
We are given that
Radius,r=1.9 m
Angular speed,
Time,t=3.5 s
Initial angular velocity,
We have to find the large torque would have to be exerted .
Where
Substitute the values
Answer:
1380 kph west
Explanation:
The resultant velocity is the sum of airplane velocity with respect to air and the velocity of wind with respect to ground. Since these 2 vectors are in opposite direction (east vs west), we will take the 20 kph east as negative
1400 west + 20 east = 1400 west + (-20)west = 1380 kph west.
