Question

a box of chocolate bars weighs 180N. Its base has an area of 0.09m2. what pressure does it exert on the ground

Answer 1

Explanation:

pressure = normal force (or weight in newtons, N) / area

P = 180N/0.09m^2

= 2000 N/m^2 or 2000 Pa (pascal units)

second answer

P = F/A

where P is pressure, F is force and A is the area up which you are exerting this force.

1 N = 1 Kg*m/s^2

Therefore:

P = 180m/0.09m^2*s^2

P = 2000 Pascals

where 1 Pascal equals 1 Newton per square meter

Answer 2

2000N/m2

Explanation:

F/A=180/0.09=2000N/m2
