Question

If your mass is 50 kg, what is your weight in kgf, and in N. If
the area of your feet is about 320 sq.cm, then what is the pressure
exerted by you on floor.?

Answer 1

Answer:

Explanation:Here, F=50kgf=50×10=500N

(i) When boy is in the lying position, then A=0.5m2

P=FA=500N0.5m2=1000Nm−2 (ii) When boy is standing on his feet, then A=2×60cm2=120×10−4m2

P=500N120×10−4m2=4.17×104Nm−2

Answer 2

As Pressure=Area / Force

So Pressure=320/50

Ans-6.4
