A resistor DECREASES the speed of current as a resistors job is to resist the flow of electrons
Answer:
C) The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Fr.
Explanation:
Yo want to prove the following equation:
![W_N=\Delta K\\\\](https://tex.z-dn.net/?f=W_N%3D%5CDelta%20K%5C%5C%5C%5C)
That is, the net force exerted on an object is equal to the change in the kinetic energy of the object.
The previous equation is also equal to:
(1)
m: mass of the block
vf: final velocity
v_o: initial velocity
Ff: friction force
F(x): Force
x: distance
You know the values of vf, m and x.
In order to prove the equation (1) it is necessary that you have C The function F(x) for 0 < x < 5, the block's initial velocity, and the value of F. Thus you can calculate experimentally both sides of the equation.

Explanation:
Given,
F = 100 , M = 25
Now, let's find the value of A
![\sf{F = MA}](https://tex.z-dn.net/?f=%20%5Csf%7BF%20%3D%20MA%7D)
plug the values
⇒![\sf{100 = 25 A}](https://tex.z-dn.net/?f=%20%5Csf%7B100%20%3D%2025%20A%7D)
Swap the sides of the equation
⇒![\sf{25A = 100}](https://tex.z-dn.net/?f=%20%5Csf%7B25A%20%3D%20100%7D)
Divide both sides of the equation by 25
⇒![\sf{ \frac{25A}{25} = \frac{100}{25} }](https://tex.z-dn.net/?f=%20%5Csf%7B%20%5Cfrac%7B25A%7D%7B25%7D%20%20%3D%20%20%5Cfrac%7B100%7D%7B25%7D%20%7D)
Calculate
⇒![\sf{A = 4}](https://tex.z-dn.net/?f=%20%5Csf%7BA%20%3D%204%7D)
Hope I helped!
