Answer:
Probably the more correct version of the story is that Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree.
Answer:
a = -5/6 m/s²
Explanation:
v² = u² + 2as
a = (v² - u²) / 2s
a = (0² - 5²) / 2(15)
a = -5/6 m/s²
This assumes the initial velocity was in the positive direction.
D is the answer

The distance to a lightning bolt can be determined by counting the seconds between the flash and the sound of thunder due to the speed of light is greater than the speed of sound
We must consider that the speed of light (3.00× 10⁸ m/s) is greater than the speed of sound (340 m/s), this is why we can first see the lightning and after seeing it we can hear it.
In order to calculate the distance we must count the time since the lightning bolt and use the speed of sound, applying the following formula:
x = v * t
Where:
- x = distance
- t = time
- v = velocity
<h3>What is velocity?</h3>
It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).
