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:
distance = 32 kilometers
displacement = 0 kilometers
Explanation:
they traveled 15 km to and back which would mean the distance they traveled is 32 km. but the displacement would still be 0 because their starting and ending points are the same.
Pat used a First Class lever.
Answer:
<h3>The answer is 0.92 m/s²</h3>
Explanation:
To find the acceleration of an object given it's initial and final velocity and time taken we use the formula
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question
v = 39 m/s
u = 27 m/s
t = 13 s
We have
We have the final answer as
<h3>0.92 m/s²</h3>
