Answer:
Below
Explanation:
First, we need to convert the dimension from cm to m before plugging it into the equation:
32 / 100 = 0.32 m
10 / 100 = 0.1 m
You can use this equation to find the pressure exerted on the ground
Pressure = Force / Area
Plugging our values in.....
Pressure = 16 Newtons / (0.1)(0.32)
= 16 Newtons / 0.032
= 500 N/m^2

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.
