What is the pressure due to a man weighing 80 kg standing on his feet? given area of his feet is 160sq.cm take g=10m/s^2

To calculate the pressure due to a man standing on his feet, we need to use the formula:

Pressure = Force / Area

1. First, we need to calculate the force exerted by the man on the ground, which is equal to his weight. The weight can be calculated using the formula:

Weight = mass * gravity

Where the mass is given as 80 kg and the acceleration due to gravity is given as 10 m/s^2.

Weight = 80 kg * 10 m/s^2 = 800 N

2. Next, we need to find the area of the man's feet, which is given as 160 sq.cm. However, we need to convert this area into square meters, as the unit of pressure is typically in pascals (Pa).

Area (in square meters) = Area (in square centimeters) / 10,000

Area = 160 sq.cm / 10,000 = 0.016 sq.m

3. Now, we can use the values obtained from the previous steps to calculate the pressure:

Pressure = Force / Area

Pressure = 800 N / 0.016 sq.m

Pressure = 50,000 Pa

Therefore, the pressure exerted by the man standing on his feet is 50,000 pascals.
