Answer:
The airplane should release the parcel m before reaching the island
Explanation:
The height of the plane is , and its speed is v=150 m/s
When an object moves horizontally in free air (no friction), the equation for the y measured with respect to ground is
[1]
And the distance X is
x = V.t [2]
Being t the time elapsed since the release of the parcel
If we isolate t from the equation [1] and replace it in equation [2] we get
Using the given values:
x = m
Answer:
The answer is "between 20 s and 30 s".
Explanation:
Calculating the value of positive displacement:
Calculating the value of negative displacement upon the time t:
That's why its value lie in "between 20 s and 30 s".
