Example

Here we have pictured a block going down an inclined plane with coefficient of kinetic friction tex2html_wrap_inline757 . Assume it is sliding to the left as shown. Calculate the acceleration, given the masses tex2html_wrap_inline781 and tex2html_wrap_inline783 .

The tension T is the same throughout the string because we're assuming that the wheel at the top of the diagram is massless and that it can turn freely (no friction).
