While standing in a low tunnel, you raise your arms and push against the ceiling with a force of 200 n . your mass is 80 kg.what
1 answer:
According to Newton`s third law, when you push against the ceiling with a force of 200 N, ceiling will also apply 200 N normal force downward on you.
As your weight is also downward force.
Therefore, when you raise your arms and push against the ceiling with a force of 200 N, the total downward force is equal to the sum of these two forces.
That is
Thus, from Newton`s third law, 984 N is upward force exert on you by floor.

Answer:
a) Tc = 750 [N] ;b) See the explanation below.
Explanation:
To solve this problem, we first need a graphical explanation of this, as well as knowing the corresponding questions. Therefore, a search was carried out in google, in the attached image we will find a graphical description of the problem.
b)
The solution of this type of problem corresponds to the use of Newton's third law, applying static which tells us that the sum of the forces in a system in equilibrium without movement must be equal to zero.
a)
In this way we can find by means of a sum of forces on the y axis equal to zero:
- 850 - 450 + 550 + Tc = 0
Tc = 750 [N]
