Answer:
2.68 hours
Explanation:
A.) Suppose the wind blows out from the west (with the air moving east). The pilot should then head her plane to northwest direction to move directly north.
B.) Given that plane flies at a speed of 102 km/h in still air. And the wind blows out from the west (with the air moving east) at a speed of 46 km/h.
The plan resultant speed can be calculated by using pythagorean theorem.
Resultant Speed = Sqrt( 102^2 + 46^2 )
Resultant Speed = Sqrt( 12520)
Resultant speed = 111.89 km/h
From the definition of speed,
Speed = distance/time
Where distance = 300 km
Substitute the resultant speed and the distance into the formula.
111.89 = 300/time
Time = 300/111.89
Time = 2.68 hours
Therefore, it take her 2.68 hours to reach a point 300 km directly north of her srarting point

Answer:
The velocity of the cart when it reaches its greatest y coordinates is 10.135m/s
Explanation:Vx=0
0=6.8m/s+(6.2m/s^2)t
t=6.8/6.2
t= 1.1secs
Vy= 12m/s +(-1.7m/s^2 )t
Vy=12 +(-1.7×1.1)
Vy=12 -1.865)
Vy=10.135m/s
