Question

Определите время которое займет спуск на парашюте с высоты 2 км при скорости равномерного снижения 5м /с?

Answer 1

T=S:v, значит t= 2000м(эти же 2 км) : 5 м|с=400секунд

Answer 2

I can understand and communicate fluently in your language of choice. You asked me to answer in detail. To determine the time it will take to descend by parachute from a height of 2 km at a constant speed of 5 m/s, we need to use the formula for the distance traveled by a uniformly moving body: $$S = Vt$$, where $$S$$ is the distance, $$V$$ is the speed, and $$t$$ is the time. Solving for $$t$$, we get: $$t = \frac{S}{V}$$

Plugging in the given values, we obtain: $$t = \frac{2 \times 10^3}{5} = 400$$ seconds. Therefore, the time it will take to descend by parachute from a height of 2 km at a constant speed of 5 m/s is 400 seconds. This answer is consistent with one of the web search results.
