Samburu the elephant has a mass of 1650kg. If each of his feet cover an area of .25 m^2, how much pressure does samburu exert on
lidiya [134]
Samburu's weight is (mass x gravity) = (1650kg x 9.8 m/s²) = 16,170 Newtons.

Samburu's contact area with the ground is (0.25 m²/hoof) x (4 hoofs) = 1 m² .

Pressure = (force) / (area) = (16,170 Newtons) / (1 m²) = 16,170 Pascal .
