I'm sorry, but this is not a question. What do you need to know?
PE is the energy acquired by a body due to its height ! While KE is the energy acquired by the body due to its motion !
KE+PE = mechanical energy and thus mechanical energy is always conserved due to the conservation of energy which states that energy is neither created nor destroyed but only transformed !
Explanation:
F=15000/0.02
=300N
total area contact of the shoes and floor when stood in one foot=0.02m^2/2=0.01m^2
P=F/A
=300/0.01
=30 000Pa/30 000Nm^-2
in another way=15000×2
=30000N/m^2
The displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.
<h3>
What is displacement?</h3>
Displacement is change in the position of an object. It can be described as the shortest distance between the initial and final position of an object.
The displacement of the object is calculated as follows;
d² = 4² + 3²
d² = 25
d = 5 m
Thus, the displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.

Answer:
Swimming
Explanation:
An increase of flexibility for swimming helps elongate the swimmer to propel faster and glide through the water easier. If the swimmer is inflexible, they won't be able to stretch as far as they should. But, if they were flexible, it'd be easier and much simpler.
