Question

С высоты 647 м парашютист равномерно опускался 3 мин 20 с. Чему равна скорость парашютиста? Скорость парашютиста равна ...м/с. (Результат округли до сотых)

Answer 1

V=S/T;
V=647/200;
V=3.2 м/с

Answer 2

Calculation of Parachutist's Speed

To calculate the speed of the parachutist, we need to use the formula:

Speed = Distance / Time

In this case, the distance is the height from which the parachutist is descending, which is given as 647 meters. The time is given as 3 minutes and 20 seconds, which can be converted to seconds as follows:

3 minutes = 3 * 60 seconds = 180 seconds

20 seconds

Now we can substitute these values into the formula to calculate the speed:

Speed = 647 meters / (180 seconds + 20 seconds)

Speed = 647 meters / 200 seconds

Calculating the value:

Speed = 3.24 meters/second

Therefore, the speed of the parachutist is approximately 3.24 meters/second.
