Question

На каком ростояний от земли оказалась бы космический корабль через 2 мин после старта,если бы во время взлета он двигался прямолинейно с ускорением 10 м/с2

Answer 1

Ответ: S= 1,6⋅104 км.

Answer 2

Distance Traveled by the Spacecraft

To calculate the distance traveled by the spacecraft after 2 minutes with an acceleration of 10 m/s^2, we can use the following kinematic equation:

s = ut + (1/2)at^2

Where: - s = distance traveled - u = initial velocity (assumed to be 0 m/s as the spacecraft starts from rest) - a = acceleration (given as 10 m/s^2) - t = time (2 minutes = 120 seconds)

Calculation

Using the given values: - u = 0 m/s - a = 10 m/s^2 - t = 120 seconds

We can calculate the distance traveled by the spacecraft after 2 minutes.

s = ut + (1/2)at^2 s = 0*120 + (1/2)*10*(120^2) s = 0 + 0.5*10*14400 s = 0 + 0.5*144000 s = 0 + 72000 s = 72000 meters

So, the spacecraft would be approximately 72,000 meters from the Earth's surface after 2 minutes from the start.
