plane traveling 200 km/hr with supplies for people 110 meters below. how many second before do they have to drop the supplies

how long does it take for an object to fall 110 meters?

No, How many seconds in advance would a plane traveling 200 km/hr need to drop supplies to his a target 110 meters below before they were over it?

To determine the number of seconds before the supplies need to be dropped from the plane, we need to take into account the distance between the plane and the people, as well as the plane's velocity.

First, let's convert the velocity from kilometers per hour (km/hr) to meters per second (m/s), since the given distance is in meters.

1 kilometer = 1000 meters
1 hour = 3600 seconds

So, the velocity of the plane in meters per second is:
200 km/hr × (1000 m/km) / (3600 s/hr) = 55.6 m/s (rounded to one decimal place)

Next, we can calculate the time it takes for the supplies to reach the people by dividing the vertical distance by the vertical velocity (assuming downwards as positive).

Distance = 110 meters
Velocity = 55.6 m/s

Time = Distance / Velocity = 110 m / 55.6 m/s ≈ 1.98 seconds (rounded to two decimal places)

Therefore, the supplies need to be dropped approximately 1.98 seconds before the plane reaches the people who are 110 meters below.
