Answer:
Keep going you are doing great, if you need a break go take a short walk
Answer:
1)
2) See below
Explanation:
1)
The system of equations that we have in this problem is:
(1)
(2)
(3)
Here we want to solve the system for .
First of all, we isolate T from eq.(2):
And we substitute this expression into eq(1):
Solving for , we get
Now we can substitute this into eq(3):
And re-arranging for we find:
2)
We see that this solution satisfies all special cases. In fact:
- If ,
- If and , we get
Also, this solution has dimensions of acceleration. In fact:
- The term at the numerator is in the form , where mass is in kilograms and g is in meters per second squared (so, it is in the form mass*acceleration)
- The term at the denominator is a mass, so it is in kilograms
This means that is (mass*acceleration)/(mass), therefore it has dimensions of acceleration.
