As a freely falling object picks up downward speed, what happens to the power supplied by the gravitational force?
vitfil [10]

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

P = \frac{E}{t}

P = \frac{F*h}{t}

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)

Calculate how far ahead of the drop zone a pilot would have needed to drop humanitarian aid packages if the delivery occurred at
ozzi

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

Is It true that if you drop a heavy object and a lighter object at the same time, they will both drop at the same time due to gr
valkas [14]

Answer:

\huge\boxed{True.}

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!
