Question

an elephant is having a mass of 1500 kg and the area of one of its weight is 50 cm square how much pressure will it apply on the ground when it is standing on all four legs

Answer 1

Mass of the elephant = 1500 kg

Acceleration due to gravity = 10 m/s^2

Weight of the elephant = mass × gravity

Weight of the elephant = 1500 × 10 = 15000 N

Area = 50 cm^2 = 0.005 m^2

Total area = 4 × 0.005 = 0.02 m^2

Now, the pressure is defined as the force acting on the per unit area.

$Pressure = \frac{Force}{Area}$

$Pressure = \frac{15000}{0.02}$

Pressure = 750000 Pascals

Hence, the pressure applied by the elephant on the area = 750000 Pascals
