Answer:
W = 1562.5 J
Explanation:
Path 1:
W₁ = F₁*d₁ = 385 N * 2.5 m = 962.5 J
Path 2:
W₂ = F₂*d₂ = 130 N * 10 m = 1300 J
Path 3:
W₃ = F₃*d₃ = (-350 N) * 2 m = - 700 J (opposite to the motion)
We get
W = W₁ + W₂ + W₃ = 962.5 J + 1300 J + (- 700 J) = 1562.5 J

Answer:
2.6 kilo Ohm
Explanation:
Capacitance, C = 591 μF = 591 x 10^-6 F
Vo = 88.5 V
V = 11.9 V
t = 3.09 s
Let the resistance is R.



Take natural log on oth the sides
ln 0.135 = - 3.09 / RC
RC = 1.545
R = 1.545 / ( 591 x 10^-6)
R = 2614.2 ohm
R = 2.6 kilo Ohm
Thus the resistance is 2.6 kilo Ohm.
Answer:


Explanation:
Given

To start with, we begin with

Substitute the expression for F


Acceleration (a) is:

So, the expression becomes:

-----------------------------------------------------------------------------------------
Velocity (v) is:
--- distance/time



--------------------------------------------------------------------------------------------
So, we have:


Divide both sides by 


Divide both sides by m


Integrate:






Next, is to get the maximum velocity by distance x.
To do this, we find the derivation by x





Divide both sides by 

Take cube roots of both sides
