We may be positive that an object is in mechanical equilibrium if it is not rotating and experiences no acceleration.

<h3>What is mechanical equilibrium?</h3>

There are numerous other definitions for mechanical equilibrium that are all mathematically comparable in addition to the definition in terms of force. A system is in equilibrium in terms of momentum if the component motions are all constant. If velocity is constant, the system is in equilibrium in terms of velocity. When an item is in a state of rotational mechanical equilibrium, its angular momentum is preserved and its net torque is zero. More generally, equilibrium is reached in conservative systems at a configuration space location where the gradient of the potential energy concerning the generalized coordinates is zero.

What would happen if the earth's core was destroyed?
Vera_Pavlovna [14]
Our atmosphere would be quickly stripped away, much like what apparently happened on Mars after its molten core cooled and solidified. The spinning Earth core is what helps create our magnetic field, without which means no Van Allen Belts, which mean solar radiation becomes more lethal than just sun burn

a box has a momentum of 1.30 kg*m/s to the right. a 12.8 N force pushes it to the right for 0.218 s. what is the final momentum
Rufina [12.5K]

Answer:

4.09 kgm/s

Explanation:

Concept tested: Second Newton's law of motion

So what does the second Newton's law of motion state?

  • According to the second Newton's law of motion, the resultant force and the rate of change of momentum are directly proportional.
  • That is; F=\frac{(mVf-mVo)}{t}, where, mVf is the final momentum and mVo is the initial momentum.

In this case;

  • Force = 12.8 N
  • Initial momentum, mVo = 1.3 kgm/s
  • Time, t = 0.218 seconds

Therefore; replacing the values of the variables in the formula;

we get;

12.8N=\frac{(mVf-1.3kgm/s)}{0.218s}

(12.8N)(0.218s)=(mVf-1.3kgm/s)

2.7904+1.3=mVf

Solving for final momentum;

mVf =4.0904 kgm/s

      = 4.09 kgm/s

Therefore, the final momentum of the box is 4.09 kgm/s
