Two boxes are seen to accelerate at the same rate when a force 3F is applied to the first and F is applied to the second. What is the mass ratio of the boxes?
f = ma
solving for a the equation is:
a = f/m
so f/m for the first mass is:
f/m for the second mass is:
these two are equal
1force/2ndmass =3 force/1stmass
(1force)(1stmass) = (3force)(2ndmass)
divide force on both sides:
(1)(1stmass) = 6mass
The second box is 6 times as massive.
