Explanation:

Newton's second law states that force is equal to the change in momentum per unit of time.

    Mathematically;

           Force  = mass x acceleration

From the second law, we find that for higher acceleration, mass must be minimal.

  Mass is inversely proportional to acceleration;

So;

 A mountain packer that packs too much gear will have a high mass and this will reduce his acceleration.

The lighter he packs, the lower his mass and the more his acceleration would be.
