Question

С какой скоростью спускался парашютист если с высоты 1.5 км он опускался на землю 5 мин (в м/с)?

Answer 1

5 мин.=300 секунд
1.5км.=1500 метров
1500:300=5 м/с

Answer 2

1,5 км= 1 500 метров
5 минут= 300 секунд
1500/300= 5 м/с

Answer 3

Parachutist's Descent Speed Calculation

To calculate the speed at which the parachutist descended from a height of 1.5 km to the ground in 5 minutes, we can use the formula:

Descent Speed (m/s) = Descent Distance (m) / Time (s)

First, we need to convert the given height from kilometers to meters: 1.5 km = 1500 m

Now, we can calculate the descent speed using the given time: Descent Speed = 1500 m / (5 minutes * 60 seconds/minute)

Descent Speed = 1500 m / 300 s Descent Speed = 5 m/s

Therefore, the parachutist descended at a speed of 5 m/s.
