Answer:
64852.94 N/m²
Step-by-step explanation:
From the question,
P = F/A.................... Equation 1
Where P = Pressure of the Elephant on the ground, F = Weight of the Elephant, A = Area of the sole of the four legs.
But,
F = mg.............. Equation 2
Where m = mass of the elephant, g = acceleration due to gravity
Substitute equation 2 into equation 1
P = mg/A............ Equation 3
Given: m = 4500 kg, A = (1700×4) cm² ( The elephant has four legs) = 6800 cm² = 0.68 m²
Constant; g = 9.8 m/s²
Substitute these values into equation 3
P = (4500×9.8)/0.68
P = 64852.94 N/m²
