Question

How much pressure does an elephant with a mass of 2200 Kg and a total footprint area of 4500 cm2 exert on the ground?

Answer 1

Answer:

47911.1 pa

Explanation:

The SI base unit of pressure is pascal, which is N/m^2.

2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.

So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.

Answer 2

Answer:

pressure =

$47911.11 \: \: pascals$

Explanation:

here's the solution :-

force = weight of elephant.

=》f = mg

( where m = mass and g = acceleration due to gravity )

=》f = 2200 × 9.8

=》force = 21560 N

( note : acceleration due to gravity is also taken as approximate 10 , unless it is not mentioned in question we are taking it as 9.8 )

Area of footprint of elephant = 4500 cm^2

=》

$\frac{4500}{10000} \: meter {}^{2}$

=》0.45 m^2

now,

=》pressure = mass ÷ area in contact

=》

$p = \frac{21560}{0.45}$

=》

$p = 47911.11 \: pascals$
