Question

A block of mass mb rest on a horizontal surface and is accelerated by means of a horizontal cord that passes over a frictionless peg to a hanging weight of mass mw. the coefficient of kinetic friction between the block and horizontal surface is u and the tension in the cord is T. The acceleration of the block is given by

A) (T - mwg)/(mw+mb)
B) T/(umbg+mb)
C) (T - umb)/(mb)
D) (mwg - T)/mw
E) T/mb - umbg
