Explanation:
Take at look to the picture I attached you, using Kirchhoff's current law we get:
This is a separable first order differential equation, let's solve it step by step:
Express the equation this way:
integrate both sides, the left side will be integrated from an initial voltage v to a final voltage V, and the right side from an initial time 0 to a final time t:
Evaluating the integrals:
natural logarithm to both sides in order to isolate V:
Where the term RC is called time constant and is given by:
Complete Question

Answer:
The value is
Explanation:
From the question we are told that
The length of the stretcher is
The weight of the stretcher is
The weight for Wayne is
The distance of center of gravity for Wayne from Chris is
Generally taking moment about the first end where Chris is
=> upward moment
Here is the force applied by Jamie
Generally taking moment about the second end where Jamie is
=> downward moment
Generally at equilibrium , the upward moment is equal to the downward moment
=>
=>
(a) 46.6 cm
To calculate the total displacement, we need to resolve each vector along the x- and y- direction.
In the following, we take:
- East as positive x-direction, West as negative x-direction
- North as positive y-direction, South as negative y-direction
Vector A:
Vector B:
Vector C:
Vector D:
So the components of the total displacement are:
So the magnitude of the total displacement is:
(b) 19.8 degrees south of west
First of all, let's notice that:
- both components x and y of the total displacement are negative --> this means that the direction of the displacement is south of west
This means that the angle will be given by
where we have
Substituting, we find
and this angle is south of west.
