Answer:
R=2F
Explanation:
As the forces are in same direction so the resultant force will be:
R=F+F
R=2F
Efficiency is completing a task as fast a possible the the least amount of effort.
What is the question? I think that you answered it yourself...
Using the formula KE=1/2mv^2
a: The kinetic energy doubles.
b: The kinetic energy quadruples.
c: The kinetic energy is cut in half.
Hopefully it’s clear how the formula can show you this.
Answer: a
Explanation: because the answer is 1.4444444 and that's the closest
