Abox 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 of the box.

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; , where, mVf is the final momentum and mVo is the initial momentum.

In this case;

Force = 12.8 NInitial momentum, mVo = 1.3 kgm/sTime, t = 0.218 seconds

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

we get;

Solving for final momentum;

      = 4.09 kgm/s

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

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
