We will start from the definition of power in terms of the Force. Power could be described as the change of energy in an instant of time. Considering that Energy is the product between the Force and the distance traveled we would arrive at the expression


Here,
F = Force
h = Height
t = Time
As there is no external force, apart from the force of gravity, and this, is constant during the course of the object we will also have to be constant power and therefore this during its course will be the same. The correct answer is (1)
Answer:
S = 11488.42 m
Explanation:
Given,
The speed of the jet, v = 0.74 Mach
= 253.82 m/s
The altitude of the jet, h = 10000 m
Since the jet is travelling horizontally, the vertical component of velocity Vy = 0
The equation for a projectile projected from a height h is given by,
S = Vx [Vy + √(Vy² +2gh)] / g
Since Vy = 0
S = Vx √(Vy² +2gh) / g
= 253.82 x √(2 x 9.8 x 10000) / 9.8
= 11488.42 m
Hence, the humanitarian aid package should be delivered ahead of distance, S = 11488.42 m
Answer:

Explanation:
This is true because gravity is independent of mass. Whether it's a heavy or a light object, when dropped, they both will hit the ground at the same time. The reason is that gravity does not depend on mass.
Hope this helped!
