Calculate the pressure exerted on the heel of a boy’s foot if the boy weighs 80 n and he lands on one heel, which has an area of 16 cm2.

Pressure at a given surface is given as ratio of normal force and area

so here force due to heel of the shoes is given as 80 N

and the area of the heel is given as 16 cm^2

so we can say

here we have

F = 80 N

so pressure at the surface due to its heel will be 5 * 10^4 N/m^2

pe = weightxheight = 2000x1000=2,000,000joules

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
