The engine efficiency is 64.73 %
<u>Explanation:</u>
Given data
To find the engine’s efficiency we have the formula,
Energy input- 4565 KJ
Energy output - 2955KJ
Efficiency= energy output/ energy input ×100%
=2955/4565
=0.6473 ×100
η =64.73 %
The engine efficiency is 64.73 %
Newtons law states F=ma
so F/m=a
in addition it makes logical sense the lighter an object the easier it is to accelerate its velocity form 0 to some quantity
The greatest percent of mass of the universe is dark matter
