Answer:
<h2>254.56 m</h2>
Explanation:
A object dropped from a plane from a certain height will follow a parabolic trajectory because it has a horizontal velocity equal to plane's velocity.
So, if supplies are to be dropped from a plane from a height of 160 m, let us calculate the time it takes to reach the ground.

So, in this time, the supply moves a horizontal distance of
.
∴ The supply must be dropped when the plane is 255 m away.
Answer:
The answer to your question is: total energy = 30100.4 J
Explanation:
Kinetic energy (KE) is the energy due to the movement of and object, its units are joules (J)
Data
mass = 1280 kg
speed = 4.92 m/s
Force = 509 N
distance = 28.7 m
Formula

Work = Fd
Process
- Calculate Kinetic energy
- Calculate work
- Add both results
KE = 
KE = 15492.1 J
Work = (509)(28.7)
Work = 14608.3 J
Total = 15492.1 + 14608.3
Total energy = 30100.4 J
<span>At first glance, it seems that it would be more work to climb the staircase with the greater incline. But on further reflection, it is obvious that climbing the complete length of each staircase involves doing the same amount of work against gravity, because the vertical distance is the same. The answer is that each involves doing the same amount of work against gravity.</span>
