Answer:

HEY MATE

Pressure, P = 26666.7 Pa

Explanation:

Mass of the boy, m = 40 kg

Its weight is, W = F= m g = 40 × 10 = 400 N

Area of contact of each shoes, A = 6 cm × 25 cm = 150 cm² = 0.015 m²

Pressure exerted on the floor by the boy is defined as the force acting per unit area.

P=\dfrac{F}{A}P=AF

P=\dfrac{400}{0.015}P=0.015400

P = 26666.7 Pa

Hence, this is the required solution.

Hope it helps

Answer:

Hello mate, first we need the two quantities force and are but we don't have them so we can initially write the quantities through which we can derive the two quantities:

Mass(m) = 60 kg

Breadth(b)=6cm=0.06m

Length(l)=25cm=0.25m

Acceleration due to gravity(g)=10m/s^2(Mostly people take it as negative but in this case we have taken it positive just for convenience)

Force=ma

Force=(60*10)N

Area=l*b

Area=(0.25*0.06)m^2

Pressure=Force/Area

Pressure=(60*10)N/(0.25*0.06)m^2

Pressure=40000Pa

Ans. The pressure is 40,000 Pascals
