Given:-

  • Mass = 75 kg

  • 280 cm² = 280/10000 m² = 28/1000 m²

To be calculated:-

Calculate the pressure exerted on a level ground.

Formula used:-

Pressure = Force/Area

Solution:-

First of all,

We have to find out Force ;

Force = m × g

Force = 75 kg × 9.8 m/s²

Force = 735 kg.m/s² [ 1 N = kg.m/s² ]

Force = 735 N

Now,

Pressure = Force/Area

Pressure = 735 / 28/1000

Pressure = 735 × 1000 / 28

Pressure = 735000 / 28

Pressure = 26,250 Pascal
