There is no horizontal acceleration, but there is an acceleration due to gravity on block W.
First you need to calculate the static force of friction on block A:
F=UsFn
F=(0.27*65.9)
F=17.793
Then you need to determine if the tension on the string from block W has enough force to move...
Homework Statement
In Eq. 38-18 Keep both terms, putting A=B=Ψo. The equation then describes the superposition of two matter waves of equal amplitude, traveling in opposite directions.(Recall that this is the condition for a standing wave.)
(a) Show that |Ψ(x,t)|^2=2Ψo^2[1+Cos(2kx)]
(b)...
