Three objects are connected on a table by massless cords as shown in the figure. The coefficient of kinetic friction between the block of mass and the table is $0\mathrm{.}25.$ The objects have masses of m$1$

$=2$ kg$,$ m$2$

$=2$ kg$,$ and m$3$

$=5$ kg$,$ and the pulleys are frictionless. Take g$=9\mathrm{.}81$ m$/$s$2.$

A$)$ Calculate the acceleration of the block with mass m$2$

in m$/$s$2.$

B$)$ Calculate the tension on the cord between the blocks m$1$

and m$2,$ in Newtons.

C$)$ Calculate the tension on the cord between the blocks m$2$

and m$3,$ in Newtons.
