Question

a man of mass 40 kg is standing on the floor. each of his feet has an area of 50 x 2.50 cm² . find the pressure exerted by him on the floor. (take1 kg wt=10N)

Answer 1

To calculate the pressure exerted by the man on the floor, divide his weight by the total area of his feet.

Step-by-step explanation:

To calculate the pressure exerted by the man on the floor, we need to use the formula:

Pressure = Force / Area

First, we need to calculate the force exerted by the man, which is equal to his weight. Since 1 kg weight is equal to 10 N, the man's weight is 40 kg * 10 N/kg = 400 N.

Next, we need to calculate the area of each foot, which is 50 cm * 2.50 cm = 125 cm². The total area of both feet is 2 * 125 cm² = 250 cm².

Finally, we can calculate the pressure by dividing the force by the area: Pressure = 400 N / 250 cm² = 1.6 N/cm².
