Two objects with a mass of 2 kg and 4 kg, respectively, are moving at a speed of 20 m / s. The momentum of each of these objects is ...

help answer the task soon

40kgm/s and 80kgm/s

Explanation:

Momentum is the amount of motion a body possesses. It is mathematically expressed as;

  Momentum  = mass x velocity

For the first body,

 Mass  = 2kg

 velocity  = 20m/s

Momentum  = 2 x 20  = 40kgm/s

For the second body;

   Mass  = 4kg

    velocity  = 20m/s

    Momentum  = 4 x 20  = 80kgm/s

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
