Question

Самолет увеличил за 16 с скорость от 240 км/ч до 720 км/ч. Чему равно перемещение самолета за это время ? с каким ускорением двигался самолет?

Answer 1

Ответ:

30км/с

Объяснение:

720-250=480

480/16=30

Answer 2

Calculation of the Plane's Displacement

To calculate the displacement of the plane, we need to determine the distance traveled by the plane during the time it took to increase its speed from 240 km/h to 720 km/h.

The formula to calculate displacement is:

Displacement = Average Velocity × Time

In this case, the average velocity is the average of the initial and final velocities of the plane.

Let's calculate the displacement:

1. Initial velocity (u) = 240 km/h 2. Final velocity (v) = 720 km/h 3. Time (t) = 16 seconds (given)

To convert the time from seconds to hours, we divide it by 3600 (since there are 3600 seconds in an hour).

Time (t) = 16 seconds ÷ 3600 = 0.00444 hours

Now, let's calculate the average velocity:

Average Velocity = (Initial Velocity + Final Velocity) ÷ 2

Average Velocity = (240 km/h + 720 km/h) ÷ 2 = 480 km/h

Finally, we can calculate the displacement:

Displacement = Average Velocity × Time

Displacement = 480 km/h × 0.00444 hours

To calculate the displacement, we multiply the average velocity by the time.

The displacement of the plane is approximately 2.13 kilometers.
