Question

the mass of a boy is 20 kg and the area of the sole of his foot is 0.01 m square if g is equal to 10 metre per second square calculate the pressure exerted on the floor when he is standing on the both feet

Answer 1

weight of man =20kg
area of sole= 0.01. square

pressure=force/area

pressure = 20kg×10ms^2/0.01
=20000kgm^-1s^-2

Answer 2

Mass : 20 kg

Area :0.01m

Velocity : 10m/s

Force= mass × velocity

= 20kg × 10 m/s

=200N

Pressure =force ÷area

= 200N ÷ 0.01 m

= 0.02 pascal
