If the coefficients of static and kinetic friction between a 20 kg block that sits on top of a 100 kg block are both essentially the same value of 0.5, determine the acceleration of each block for a force pulling on A of 60 N. Bottom block sits on a friction-less floor.

Question

If the coefficients of static and kinetic friction between a 20 kg block  that sits on top of a 100 kg block are both essentially the same value of 0.5, determine the acceleration of each block for a force pulling on A of 60 N. Bottom block sits on a friction-less floor.

(I was able to figure out that block A accelerates 1.095 m/s^2 in the +x direction...but I cant seem to figure out acceleration for bottom block, block B.)

@Sipho, if you'd like to continue using this site you may need to limit the kinds of post you are making. "Shut up" is not an effective response to a question you may not understand. You might want to not write anything and just shut up.
