Well without energy we would have no oil, electricty or anything. I mean we need electricty for computers, phones, ovens, cars and so many more. Energy literlaly powers almost everything in the world! So the world would become a place where everyone would have to do things on thier own. They have to build fires to cook food, they have to wash their own clothes, they have to do all these things on their own instead of relying on electricty!
Hopefully this helps! :)

Answer:
87.5mph
Explanation:
Given parameters:
Acceleration = 7.5mph/s
Starting speed = 50mph
Time = 5s
Unknown:
Final speed = ?
Solution:
Acceleration is defined as the rate of change of velocity with time:
Acceleration = 
Insert the parameters and solve;
7.5 = 
Final speed - 50 = 7.5 x 5
Final speed = 7.5 x 5 + 50 = 87.5mph
The kind of investigations might have led to our current understanding of matter and energy is research and measurement.
It is important for scientists to use the same scientific method and consistent measurement units in order to get the correct value while analayzing.
<h3>What is matter?</h3>
The matter has volume and space occupied.
When conceivable the researcher endeavors to test his speculations via painstakingly planned and controlled tests that will yield quantitative instead of subjective outcomes.
Thus, the kind of investigations might have led to our current understanding of matter and energy is research and measurement.
It is important for scientists to use the same scientific method and consistent measurement units in order to get the correct value while analayzing.
