In physics<span>, a force is said to do </span>work if, when acting, there is a displacement of the point of application in the direction of the force. <span>Nonconservative force for this question refers to FRICTIONAL force. </span>
<span>By conservation of energy, </span>
<span>Work done by Frictional force = Kinetic energy = 1/2(17000)(82)^2 = 57MJ </span>
Might of had a different magnitude.
I think, it must be a chemical. Because the fire is a chemical reaction. So, the chemical energy converted to heat energy.
Answer:
x coordinate = -1.66 m
y coordinate is = -0.825m
Explanation:
Suppose z be the distance form the first charge and z + sqrt(1^2 +.5^2) be the distance from the second So z + sqrt(1+.25) = z + 1.12
We have k*2.0x10^-6/s^2 = k*6x10^-6/(s+1.12)^2
0.0356s^2 -0.019s-0.0897=0
s=1.876m
The angle of the line between the two charges is arctan(.5/1) = 26.6o
x coordinate = -1.876*cos(26.6) = -1.66m
y coordinate is -1.876*sin(26.6) = -0.825m
