Hello, I am looking for the equation to solve this problem:
1. A .75 kg object with dimensions 24 and 20 are on a table.
What force does the object apply to the table? What pressure does the book apply?
Thanks!
Force = Mass * Acceleration (or in this case, gravity)
F = (.75kg)*(9.8m/s^2)
F = 7.35
Pressure = Force/Area
p = 7.35N/(??)
I am going to assume that the dimensions 24 and 20 are in meters and refer to a box.
The surface area of a side of a box is 24*20 = 480m
so
p = 7.35/480
p = 0.0153125 :)
