Calculate the displacement of an air craft that travels due north for 78minutes at 720km per hour
D = V*T = 720km/h * (78/60)h = ___km.
To calculate the displacement of an aircraft, we need to use the formula:
Displacement = Velocity × Time
In this case, the aircraft is traveling due north, which means its displacement is in the north direction only. The given speed is 720 km/h, and the time is 78 minutes.
However, before we can use the formula, we need to convert the time to hours since the speed is given in kilometers per hour.
To convert minutes to hours, we divide by 60:
78 minutes ÷ 60 = 1.3 hours
Now we can use the formula:
Displacement = Velocity × Time
Displacement = 720 km/h × 1.3 hours
Displacement = 936 km
So, the displacement of the aircraft is 936 km to the north.
