What is the relationship between surface area and bulk modulus in a collision?

[jkhc23]

Homework Statement

bulk modulus

Relevant Equations

bulk modulus, pressure.

there are two materials:
Material A
Material B
surface area A/surface area B= 30

bulk modulus B/bulk modulus A= 11

How much more pressure is exerted through material B than material A in a collision, all else being equal?

Welcome to the PF.

Homework Statement:: bulk modulus
Relevant Equations:: bulk modulus, pressure.

there are two materials:
Material A
Material B
surface area A/surface area B= 30

bulk modulus B/bulk modulus A= 11

How much more pressure is exerted through material B than material A in a collision, all else being equal?

What is the equation for the Bulk Modulus? What equations can you list to describe pressure?

(And if these two surfaces have different surface areas, how can they be pushing on each other?)
