Question

Calc-based physics problems, need help!

Answer 1

ok

Answer 2

Two blocks (labeled A and B ) remain together as they are pulled to the right by a force F acting on block A. The mass of block A is Ma and the mass of block B is Mb. The coefficient of kinetic friction between block B and the horizontal surface is \[\mu \]k.

a) Draw a FBD for each block and the combined system.
b) identify any Newton's 3rd law force pairs.
c) what is the acceleration a of the system? Express your answer algebraically in terms of Ma, Mb, g, F, and uk.
d) If the static friction force between blocks A and B is a maximum, what is the coefficient of static friction Us between the two blocks? Express your answer algebraically in terms of Ma, Mb, g, F, and uk.

Answer 3

ok, lets see what your sketch of the problem looks like.

Answer 4

or perhaps there is already a digram in your book for the problem you can post
