1. If the acceleration of a pair of boxes has a magnitude of 2.5m/s^2, determine the smallest coefficient of friction between the boxes that will prevent slippage.
F = ma
Fk = ukFn
Fw = mg
ma = uk mg(Fn)
a = uk g
a/g = uk
2.5m/s^2 / 9.8m/s^2 = uk
uk = 0.25
Homework Equations
F = ma
Fk = ukFn
Fw = mg
The Attempt at a Solution
ma = uk mg(Fn)
a = uk g
a/g = uk
2.5m/s^2 / 9.8m/s^2 = uk
uk = 0.25
